If you want to know the details of how SIP trunking works, then I will explain here everything you need to know and the process too.
What Is SIP Trunking?
A SIP trunk is an essential system of virtual bundles of voice channels carried over IP by using SIP. It works for the setup, management, and tear-down of phone calls. Otherwise, traditional copper phone lines aren’t like these. It’s costly, a maintenance hassle, and has weather-related issues. That’s why people are moving to the SIP or internet-based communication system.
Key advantages:
Scalability: You can add or remove channels on demand.
Cost Efficiency: pay per channel or minute, no physical lines.
Feature-Rich: Leverage advanced call routing, disaster recovery, and codecs.
Core Components & Roles
IP-PBX or Hosted PBX Your on-prem or cloud-hosted telephony platforms, such as Free PBX, Cisco CUCM, 3CX, or our Cloud PBX that manages extension, call routing, and voicemail, etc.
Session Border Controller (SBC) Acts as a security and interoperability gatekeeper that hides your internal IP scheme, enforces encryption, and applies SIP normalization
Internet Telephony Service Provider (ITSP) The Voice providers that terminate calls to the PSTN or other SIP networks and allocate you a pool of DIDs with the voice channels.
Media Path (RTP/RTCP) Carries actual voice packets, typically RTP with RTCP for quality control. It may traverse a separate media proxy or go peer-to-peer via NAT traversable techniques.
Well, VoIP is the technology that businesses use to communicate. As well, SIP is the methods or protocol that execute its technology for terminating voice.
If I want to be more clear with the real thought, I think VoIP is a car and SIP is the engine of this system.

How SIP Trunking Works The Process
Let’s break down step by step what happens when you make a VoIP Call through SIP trunking.
1. Call Initiation (SIP Signaling Begins)
The moment you dial a number, your IP PBX generates a SIP INVITE message.
This INVITE packet includes:
Caller ID
Callee’s number
Codec preferences
Authentication details
Then the message reached the SIP provider such as MondoTalk, Ufonii, or Twilio.
2. SIP Trunk Authentication and Routing
The provider receives your INVITE and authenticates it for use with username/password. This authentication will be IP-based. I mean whitelisted IPs. Once authenticated, the SIP server then checks the destination numbers and chooses the best route.
3. Media Negotiation (RTP Stream Setup)
SIP only sets up the session, and voice is sent via RTP( Real Time Transport Protocol).
Once the destination accepts the call, like a SIP 200 OK, both parties start sending voice data as audio packets.
RTP ports that are typically 10000-20000 open up dynamically, and NAT traversal or STUN/TURN are used if needed.
4. Call Connection and Ongoing Session
During the call:
SIP monitors session health via OPTIONS and SIP keep-alives.
Media streams flow back and forth using RTP.
Features such as DTMF tones, call recording, or transferring are also handled via in-band RTP or SIP info/notify messages.
5. Call Termination
Either party hangs up: sends a SIP BYE message.
Provider replies with 200 OK, confirming the call is terminated.
Call Detail Records (CDRs) are generated for billing and logs.
Voice quality is monitored in real-time via MOS scoring.
CDRs sync into Zoho CRM for call reports.
Personal Experience Insight:
We once had intermittent audio drops on rainy days. It turned out to be a poor-quality router at the retail site doing SIP ALG rewrites. We replaced it with a proper SIP-friendly route,r and the issue disappeared.
Example: Legal Firm
Helped a mid-size legal firm with 75 extensions replace their aging PRI circuits with a pair of redundant SIP trunks. They’d been paying for 23 channels on two ISDN PRIs.
Preparation Steps:
Bandwidth Assessment
Run a year’s worth of call logs and peak concurrent calls: 18. It allocates 100 kbps per G.711 call, 1.8 Mbps plus overhead, and 3 Mbps reserved.
SBC Deployment
Installing an on-premises SBC and configuring TLS on port 5061. It defined IP ACLs so that only the ITSP’s signaling IPs could connect.
PBX Configuration You can create two outbound trunks on the PBX:
SIP-Primary (UDP/5060, priority 1)
SIP-Backup (TCP/TLS/5061, priority 2): Set up inbound routes mapping each DID to a departmental ring group.
Test Calls & Failover
Then you can verify calls over SIP primary to PSTN. The system simulated failure by shutting off the primary, and calls seamlessly failed over to the backup.
Monitoring & QoS
Then configure SNMP polling on the SBC for call count, SIP errors, and set diffServ DSCP EF for RTP and CS3 for SIP to prioritize voice.

Personal Expertise: Lessons from the Field
Never underestimate the power of good call logs. If there is a SIP 503 or 408 error, then reading the SIP invite header, RTP latency, and timing in Wireshark has solved countries
Carrier Hops Matter: A poor SIP provider might route your call through 4-5 unnecessary hops, creating jitter, which reliable providers like Ufonii route more directly.
Don’t DIY NAT Traversal: Always use proper NAT rules and test with external SIP test tools like sipvicious or VoIPmonitor.
Real Call Center Experience: A major partner once migrated from ISDN to SIP trunking. Then the experience with SIP trunk, such as post migration, and they were able to slash their monthly bill by 40%, and they were able to add auto call routing and enable CRM integration.

Final Thoughts
SIP trunking is the backbone of the modern communication system.. Behind this scene, there are lots of dependencies such as a symphony of protocols, routing, codecs, and media negotiation. The beauty is in how many moving parts come together to make a simple” hello ”work. I mean it started from INVITE packets to RTP streams and from NAT traversal to carrier selection.
When it works well, it feels like magic.
FAQs
What happens when I make a SIP trunk call?
When you make a SIP trunk call, your phone system sends a SIP invitation packet to your VoIP provider. This includes the dialed number, caller ID, and preferred audio settings. The provider routes the call to the destination, and once answered, media flows directly via RTP. SIP keeps the session alive, monitors connection health, and handles call termination when either party hangs up.
How does SIP trunking connect to the public telephone network (PSTN)?
That’s a great question. Generally, SIP trunking connects to the PSTN via your VoIP provider, which acts as a gateway. Once your call reaches the provider’s SIP servers, it is routed through their carrier network and translated into a traditional phone call that can be handled by legacy telephone systems. It enables the voip to make landline or VoIP to mobile calls seamlessly.
Is SIP trunking secure?
Yes, SIP trunks are secure for businesses. But it requires a proper setup before using. SIP trunking generally uses protocols like SIP over TLS and SRTP to encrypt signaling and media streams. Session border controllers also help protect against fraud, unauthorized access, and DDoS attacks. The firewalls should be configured to avoid exposing SIP ports unnecessarily.
Why is RTP used in SIP trunking, and what is it?
RTP( Real Time Transport Protocol is used to carry the actual voice data once a call is established. While SIP handles the signaling, RTP transmits the audio packets in real time. The separation ensures flexibility and allows for better quality control and troubleshooting.
What are the most common issues with SIP trunking?
The most common SIP trunking issues include:
One-way or no audio. It usually happens due to NAT/firewall misconfiguration.
Call drops (caused by SIP timeouts or router issues)
Codec mismatches
SIP ALG interference on routers
How many calls can a SIP trunk handle?
A single SIP trunk can support multiple concurrent calls, it’s depending on your provider and bandwidth. Each simultaneous call typically requires around 100 Kbps with the G.711 codec, so your internet connection and trunk plan determine the actual capacity. Businesses can scale easily by increasing call channels.
What equipment is needed for SIP trunking?
To use SIP trunking, you typically need
IP PBX such as 3CX, FreePBX, and Cloud-based PBX
A router and a stable internet connection
SIP trunk provider credentials
VoIP phones, softphones, or analog phones with ATA adapters
As businesses grow, communication demands often increase exponentially. Traditional telephony solutions, such as PRI lines or analog circuits, require purchasing additional channels or phone numbers for every new location or burst in call volume that leads to steep incremental costs.
Session Initiation Protocol (SIP) trunking offers an alternative by leveraging an IP-based network carrying voice, video, and messaging. Organizations can add to the demand for capacity. There is no need for any physical lines. SIP trunking helps businesses to scale their growth with seamless communication and minimize costs.
What Is SIP Trunking?
SIP (Session Initiation Protocol): It’s a signaling protocol that is used to initiate, maintain, and terminate real-time sessions that include voice, video, and messaging.
Trunking: it’s a shared communication path that uses multiple carriers to call simultaneously between an enterprise PBX and the public telephone network.
SIP Trunk: A virtual replacement of traditional trunks such as T1/E1 PRI circuits. That means instead of sending voice via dedicated lines, SIP trunk transports voice over the IP network connection. Typically, the same internet or MPLS link is used for data.
Virtual Channels vs. Physical Lines: With legacy setups, each additional call path required its physical circuit, such as a T1 line, providing 23 simultaneous calls. In contrast, SIP trunking uses dynamic allocation of channels over IP, allowing you to scale up or down by simply adjusting how many concurrent sessions your provider reserves on their side. To complete their work, you don’t need any technician visits and don’t need new wiring costs.
Capacity & Multiplexing: Rather than being limited to a fixed number of physical channels, SIP trunk providers typically allow businesses to purchase blocks of concurrent call licenses, such as 10, 20, or 50 channels. If a company rarely uses more than 10 simultaneous calls, they pay for those 10 slots. Even if their network bandwidth could accommodate 30.
By consolidating multiple traditional phone lines into a single, scalable IP-based connection, SIP trunks allow organizations to allocate channels (voice sessions) as needed dynamically.
Must provision new physical circuits or cards; lead times can be weeks or months.
Provision new channels (“channels” = concurrent call sessions) instantly via software-configurable alerts.
Channel Allocation
Fixed number of voice channels per PRI (e.g., 23 B-channels on a T1).
Pay-per-channel (on-demand allocation); no hard limits beyond bandwidth.
Geographic Flexibility
Tied to physical location; separate trunks needed for each branch.
Any branch or remote worker with a broadband connection can register to the same SIP trunk.
Disaster Recovery
Requires redundant physical circuits or complex failover configurations.
Built-in redundancy via carrier network; can failover to alternate sites or BYOD phones over IP.
Cost Structure
Capital expense for equipment + recurring fixed monthly fee per circuit.
Operating expense based on usage (per channel, per minute) + monthly SIP service fee; no hardware CAPEX.
Number Portability
Often requires local termination in each region.
Virtual DID (Direct Inward Dialing) numbers can be assigned anywhere geographically.
Key Components and Architecture
IP-Enabled PBX (On-Premises or Cloud-Hosted):
Converts internal telephony signaling (e.g., SIP, H.323) into IP packets.
Handles call control, IVR, extensions, voicemail, and call routing.
Session Border Controller (SBC):
Acts as a demarcation point between the enterprise network and the carrier’s SIP network.
Provides security, transcoding, protocol normalization, and traffic shapers to ensure call quality.
Internet/MPLS/Broadband Connection:
The underlying transport for SIP traffic. Bandwidth should be sized to accommodate peak concurrent calls (≈60 kbps to 100 kbps per call, depending on codec).
Quality of Service (QoS) or traffic-prioritization features on routers help maintain voice quality.
SIP Trunk Service Provider (ITSP):
Provides SIP trunks (virtual channels) and routes outbound calls to the PSTN (Public Switched Telephone Network).
Supplies DID numbers, E911 routing, and supports failover across data centers or regions.
PSTN Termination Gateways (Inbound/Outbound):
This is typically managed by the SIP trunk provider, converting VoIP calls into traditional circuit-switched PSTN calls when dialing Phones.

Dynamic Channel Allocation
On-Demand Provisioning: Purchase or enable additional concurrent-call channels in minutes via an online portal or API. Enable additional channels in a minute via an online portal or API.
Burstable Capacity: During peak periods (e.g., marketing campaigns, conferences), you can temporarily “burst” above your normal channel allocation rather than paying for unused capacity the rest of the month.
Geographic Independence
Any-to-Any Registration: Remote offices, satellite locations, or work-from-home employees can register to the central SIP trunk via secure VPN or SBC.
Global DIDs & Local Presence: Getting the local numbers in multiple locations without setting up physical sites. It’s great for SIP and that way facilitates expansion into new markets without local PBX infrastructure.
Unified Communications Integration
Converged Voice, Video, and IM: SIP trunking can carry voice, video, and presence signaling over a single connection. It allows simultaneous scaling of multiple media types without a separate infrastructure.
Collaboration Services: An easy integration of WebRTC softphones and cloud-hosted UC Platform means the user count can grow without additional trunk provisioning.
Redundancy & Failover
Carrier-Level Redundancy: MondoTalk provides SIP and runs geographically dispersed data centers. If one data center or trunk cluster fails, the call automatically fails over to another and doesn’t need any manual intervention.
Disaster Recovery Configurations: Configure automatic rerouting of all inbound calls to alternate PBXs, Australian, voicemail, or mobile numbers during an outage. All are going through the internet, and don’t need physical spare circuits.
Cost Efficiency and ROI
Reduced Capital Expenditure
No Additional PRI/Analog Hardware: Then eliminate the need for pricey T1/E1 cards, DS3 multiplexers, or analog gateways. Honestly, most modern IP-PBXs can handle SIP trunks natively.
Lower Maintenance: fewer physical circuits, which means fewer service costs. The result is fewer site visits by telco technicians and less hardware.
Predictable Operational Expenses
Pay-As-You-Go Model: Instead of paying for 23 channels whether they’re used or not (as with a T1 PRI), you’re billed only for the concurrent sessions you provision or use.
Included Toll Bypass: With the SIP trunking, calls between offices to cloud providers can travel over the internet, bypassing toll charges entirely.
Lower Per-Minute/Toll Rates
Wholesale VoIP Pricing: SIP trunk providers frequently offer significantly lower per-minute rates for inbound and outbound calls compared to traditional carriers.
Volume Discounts: As your call volume grows, many providers reduce minute fees and reinforce cost savings.
Consolidation of Voice & Data Networks
Single Connection: By converging voice and data onto the same MPLS or internet pipe, you avoid leasing multiple universes of circuits.
Simplified Management: One IP-only network means fewer carriers to manage, simplified billing, and reduced complexity in network architecture.
Advanced Features Enabling Cost Savings
Codec Flexibility & Bandwidth Optimization
Adaptive Codec Selection: Support for G.711, G. 729, Opus, and other codecs, which can be negotiated dynamically based on network conditions, allowing fewer bits per call without sacrificing intelligibility.
Low-Bandwidth High-Quality Options: Particularly beneficial for remote locations or international branches with limited internet connections, which reduces the incremental cost of bandwidth upgrades.
Number Portability & Local DID Routing
Port Existing Numbers: Bring your current phone numbers to the SIP providers, avoiding the expense and business disruption of reprogramming marketing collateral or customer contracts.
E911 Compliance & Enhanced 911 Routing: Automatically route 911 calls to the correct PSAP (Public Safety Answering Point) without installing block-of-lines for every site.
Flexible Billing Models
Channel-Based Billing: Many providers bill per active session; if you only need 10 concurrent calls most of the time, you pay for 10 channels. During a big product launch, you might “burst” to 20 channels for a promotional period and incur a small surcharge, rather than permanently paying for 20 channels.
Minute-Plus-Channel Blended Plans: Bundle a certain number of inbound minutes with channels to lower overall service costs, ideal for high-volume inbound call centers.
Unified Contact Center Capabilities
Cloud-Hosted Contact Center Integration: Instead of purchasing separate toll-quality trunks for every agent location, you can centralize call processing in the cloud, reducing the cost per agent as you expand. Using the cloud, you don’t need to purchase a separate toll-quality trunk for every agent.
SIP-Enabled IVR & Auto-Attendants: Host your Interactive Voice Response(IVR) in the cloud and reduce the on-prem hardware and maintenance.
Implementation Considerations
Network Readiness & QoS
Bandwidth Assessment:
Verify that your existing WAN or Internet link can support your anticipated peak concurrent calls.
Rule of thumb: G.711 uses ~80–100 kbps per concurrent call (up/down). G.729 uses ~25–35 kbps.
Quality of Service / Traffic Prioritization:
Configure your edge routers to prioritize SIP signaling like UDP/TCP ports 5060–5061 and RTP like UDP ports, e.g., 10000–20000, to minimize jitter and packet loss.
Apply DSCP tags (e.g., EF for voice) on voice packets to give them higher priority over general data. Apply DSCP tags, ex. EF for voice, on voice packets to give them higher priority over general data.
Security & SBC Deployment
Session Border Controller (SBC):
Must be placed in the DMZ to inspect and normalize SIP traffic, providing NAT traversal, and enforce anti-toll fraud measures.
Some cloud providers offer hosted SBC services, reducing on-site hardware.
All the Encrypted calls reduce the risk of eavesdropping, especially important when employees work from home or in public places.
Regulatory & Compliance
Privacy & Data Protection:
For industries subject to HIPAA, GDPR, or PCI-DSS, confirm that the SIP trunk provider complies with relevant data-protection standards.
Disaster Recovery & Failover Planning
Secondary SIP Trunk or PSTN Fallback:
In the event of primary SIP trunk failure, configure automatic failover to a secondary trunk or, if necessary, traditional PSTN lines.
Alternate Routing to Mobile or Cloud:
For critical inbound lines (e.g., 1300 numbers), set up rules to reroute calls. When mobile devices or cloud-hosted voicemail/IVR are unreachable.
To mobile devices or cloud-hosted voicemail/IVR when on-prem systems are unreachable.
Real-World Use Cases
Multi-Site Retail Chain
Challenge: A regional retailer with 50 stores across three states needed to support local store calls, centralized customer service. They need online order call-back functionality, but new PRI circuits took weeks to provision and were costly, which are $600–$800/month each.
Solution: After that deployed a centralized IP-PBX in their data center, connected via SIP trunking to the carrier. Each store’s existing broadband connection was used to register 1–2 softphones for local store managers to handle high-volume calls.
Result:
Reduced monthly telephony spend by 60% and eliminated 12 PRIs.
Provisioned new concurrent channels in 10 minutes when seasonal call volume spiked.
Gained central visibility of all inbound/outbound calls via a single SIP trunk portal.
Fast-Growing Tech Startup
Challenge: A fintech startup rapidly added employees in North America, Europe, and Asia. They needed local phone numbers to convey global presence, without building telecom closets in each location.
Solution: They purchased virtual DIDs in Canada, the UK, Germany, and Singapore from their SIP trunk provider. Its employees installed softphone apps, desktop/mobile, that registered back to the same SIP trunk. Then, all calls, regardless of origin routed through the central SIP infrastructure.
Result:
Added new local DIDs in 24 hours (vs. 2–4 weeks typical lead time for local PSTN).
Scaled from 10 to 150 concurrent calls (all over one MPLS link) within a quarter.
Saved over USD 30,000 in upfront telecom gear and cut monthly line charges by 70%.
Distributed Contact Center
Challenge: A customer support BPO had agents working from multiple home offices. They needed consistent call quality, compliance, and rapid headcount scaling for season peaks.
Solution: Then, they implemented a cloud-hosted contact center platform integrated with a SIP trunk provider. Agents used softphones or WebRTC clients. Calls from end customers entered via the SIP trunk into the cloud platform, which then distributed them to available agents.
Result:
Zero capital outlay for new telephony hardware or branch site expansions.
Increased agent headcount from 50 to 200 within two weeks for the holiday season, simply requested additional channels from the provider’s portal.
Achieved 99.99% uptime via the carrier’s multihomed data centers.
Scaling From 20 to 200 Users: Legacy Approach
Hardware Purchase: If you wanna to add more 180 users, the company might need a PBX upgrade. And that is why a new expansion will be $15,000 plus licensing fees per extension.
New Local Loops: Each office location needs additional T1/PRI circuits. At $500-$100 per month, T1 thought it depends on the region. And each T1 offering 23 channels, the enterprise may require 8 T1s, which means 184 channels and a monthly $4,000-$8,000.
Maintenance & Support: New lines mean new support contracts, potential forklift upgrades down the road, and additional power requirements.
SIP Trunking Approach
Minimal Hardware Upgrades: If the existing IP PBX can handle 200 concurrent registrations, there is no need for new physical modules. If the hardware is maxed out, a modest server upgrade of $3,000 might suffice.
Subscription Changes: The IT department simply calls the SIP provider to expand from 10 concurrent channels to 50 or 100. And then they purchase an additional 100 channels if needed. And Exciting that the cost might be $20 per channel per month.
Example: 200 concurrent channels could cost around $4,000/month. However, versus paying $6,000/month spread over four separate T1s. The SIP model can still offer savings. Especially as you factor in call bundles and lower international rates.
Common Misconceptions
“SIP Trunks Are Only for Large Enterprises.”
In reality, many SMB focused providers offer pay-per-channel plans. A small office needing only 2-5 channels can benefit from lower per-minute rates and no longer-term circuit contract.
“Voice Quality Over the Internet Is Poor.”
With proper QoS, bandwidth sizing, and use of codecs like G.722 or Opus, SIP calls often equal or exceed the clarity of T1/PRI voice.
“SIP Trunks Are Unreliable.”
Modern carriers run redundant, geo-distributed SBCs. By using multiple SIP providers, you can achieve “five nines” of availability without expense.
“VoIP is less secure is not true.”
While you are using an unsecured SIP, deployed can be vulnerable. Toll fraud and eavesdropping, industry best practices such as TLS/SRTP encryption, strong firewall rules, and SBC-enforced ACLs that effectively mitigate the risks. As MondoTalk, Many providers perform continuous SIP fraud monitoring on their network edges.
Step-By-Step Checklist for Migrating to SIP Trunking
Assess Current Environment:
Count existing concurrent voice channels, such as the number of simultaneous incoming/outgoing calls.
Configure inbound routing rules (DID to extension, IVR, or hunt group).
Set outbound dial plans to route 9 + number (or E.164 formatting) through the SIP trunk.
Testing & QoS Validation:
Place test calls like local, long-distance, toll-free, international, and verify audio clarity, one-way audio issues, and DTMF performance.
Monitor MOS (Mean Opinion Score) or R-factor metrics via the SBC or PBX CDR logs.
Cutover & Decommissioning:
Gradually phase out PRIs or analog circuits as SIP calls stabilize.
Redirect inbound numbers to the SIP trunk in DNS or through carrier porting.
Repurpose or retire old telephony gateway hardware for complete CAPEX reduction.
Ongoing Monitoring & Optimization:
Implement 24×7 alerting on packet loss, jitter, and MOS below threshold.
Review monthly usage reports:
Rebalance channel counts if over- or under-provisioned.
Identify fraud attempts like unusual call patterns or spikes.
Additional Business Benefits
Global Presence Without Physical Offices
Roll out local DIDs in target markets such as the U.K., Australia, and Germany to make it easier for customers to reach your business without incurring international dialing fees. All calls terminate on your central Cloud PBX, so you can maintain brand consistency and centralized control.
Enhanced Disaster Recovery & Continuity
In the event of a site outage, such as a natural disaster, building power loss, your cloud PBX can automatically reroute inbound calls to cellular numbers, another office, or even a headset-equipped remote worker using the same SIP trunk credentials.
Unified Communications & Collaboration
SIP trunking often serves as the backbone for broader UCaaS deployments. Once voice is carried over IP, IT becomes trivial to integrate presence, instant messaging, video conferencing, and even screen sharing. Because all these services share the same IP network, incremental costs to introduce new collaboration features are low.
Simplified Vendor Management
Rather than juggling multiple contracts with local providers in every country, you consolidate voice data and internet services with fewer providers. The result is fewer points of contact, simple billing, and often strong negotiation leverage.
Conclusion
SIP trunking empowers businesses to grow their communications infrastructure in lockstep with operational demands without incurring the disproportionate expenses associated with traditional circuit-based telephony. By leveraging existing IP networks, dynamic channel provisioning, and flexibility.
Day by day, the business is going to be competitive worldwide. At the communication level, it’s hard to scale up a business if you aren’t perfect. Here MondoTalk offers solutions for better communication levels that are important for businesses.
In this position, most businesses don’t fit with the budget because perhaps the costs of a quality communication system are high or not usable in the beginning. It’s a system that can directly affect your business efficiency.
Now it’s time to move into a cloud PBX system that effectively leads your communication system and impacts your business growth.

What is Cloud PBX?
Cloud PBX is a virtual phone system that operates over the internet. It is so smart rather than using traditional on-premise hardware. It helps business to manage their communication system well. The system works through the cloud which is maintained by the providers.
How Does Cloud PBX Work?
Cloud PBX works to build a business communication system and connect to a high-quality VoIP network. It utilizes the routes through the internet.
Let’s step by step break down how it works:
Call initiation: When a user makes a call, it converts voice into digital packets.
Internet Transmission: These packets are transmitted over the internet to the cloud PBX system.
Call routing: The provider directly calls the recipient based on configuring rules
Call completion: The recipient’s phone rings and the digital signal is converted into audio.
Integration with Unified Communications (UCaaS): Cloud PBX System will merge the seamless other communication system such as messaging, video conferencing, and CRM tools. It reduces the need for multiple communication platforms. Businesses will save on licensing costs by consolidating services into the cloud-based solution.
Savings Hardware Costs: If you are in a traditional phone line that supports your communication, think about it, you need a line. It can any time cut off or trouble your communication system. Also, you have quality issues because of traditional maintenance. It might be affected by the storm, environment, and session of the years.
So, hope you understand that you need a system that gives you a structure of communication by filling these gaps.
Now here I will talk about a Cloud communication system which is a cloud-based network for communication.
Cloud PBX is hosted in a remote server and its maintained by the provider. It’s a cloud cloud-based system where you don’t need hardware, unit bills or server costs. Just need an internet-connected device to make and receive calls.
Savings in Maintenance and IT Expenses: Maintaining an on-premise pbx system is costly because you need an in-house IT team. Also, you have to connect with an eternal technician to handle repair, upgrade, and after-all system maintenance.
On the other hand, Cloud PBX can reduce the cost of maintenance. It replies to the provider. Most importantly, you don’t need a dedicated team after all.
At the end of the day, you can save operation expenses.
Call Cost Reduction: Cloud PBX uses VoIP technology that significantly cuts the cost of local and international calls.
Many providers offer unlimited calling plans and lower expenses. That is a huge comparison between traditional phone service.
This is a one-time package and you can use it for unlimited calls and connect to any country to develop business communication.
It charges cutting by the per minute talk which is very good for international communication, specifically for business-grade communication.
Scalability Without Additional Costs
Cloud PBX system gives you an allowance for instant growth and scalable for your communication system. It can add or remove the users without any additional cost to the system. By the way, if you make any updates, there is no chance of hitting the communication network.
In other words, if you look at the traditional network, you need to connect the additional system and the cost will be high.

Remote Work and BYOD Savings
VoIP is a gold opportunity for businesses. It helps you to handle your communication with remote employees. That’s finally a great things that impact to the overall growth of businesses. It saves your office costs, communication costs, time, and staff maintenance costs.
You can hire anyone with an affordable salary.
That’s the great side for businesses because it reduces the cost of office and desk, infrastructure which is a significant saving.
No Downtime or Disaster Recovery Costs
Traditional phone systems are based on hardware connectivity which has some issues for disaster. Also, have some downsides which failure the connectivity.
Now, it’s time to fix the issues and get relief for a better communication system. Move on to the cloud PBX system, some reasons have of us. But the main ones are great, They can’t be cut of weather and don’t need maintenance costs.

“Inactive Account” means an account on which no call activity (no successful inbound or outbound calls recorded by our systems) has occurred for a continuous period of ninety (90) days.

This Agreement covers the terms and conditions that apply to the voice over Internet Services that MondoTalk provides to You, our Customer. If You buy the MondoTalk VoIP Equipment and Services through MondoTalk affiliates or third party providers, You are the Customer, along with anyone using our Service, with or without Your consent.
BY SIGNING UP FOR, PAYING FOR, OR USING THE SERVICE, YOU REPRESENT THAT YOU ARE OF LEGAL AGE TO ENTER INTO THIS AGREEMENT AND THAT YOU HAVE READ AND UNDERSTAND FULLY THE TERMS AND CONDITIONS OF THIS AGREEMENT.
MondoTalk may modify or cancel Service or take corrective action at any time without prior notice as a result of Your violation of any of these terms and conditions. Terms and conditions may change from time to time, so please check the MondoTalk website, www.MondoTalk.com to stay up-to-date.
You agree not to Use MondoTalk Services in any way that is illegal, fraudulent or abusive as determined by MondoTalk. You may not alter any of the hardware or software on Your MondoTalk Equipment and/or Services.
2. Service
Quality of Service may be affected by conditions beyond our control, including atmospheric, geographic, or topographic conditions, Internet Service Providers, Wholesale Carriers, and/or Power outages. We do not warrant or guarantee that Service will be available at any specific time or geographic location, or that Service can be provided without interruption.
For this Service to work properly, You must have the MondoTalk Equipment and Services and access to the Internet.
Service interruptions will occur when a User account has a negative balance.
The Services are offered on a prepaid basis and recurring billing periods. User accounts that are subject to a recurring service charge are paid by Automatic Debit without further action taken by You. You hereby authorize such charges. Automatic Debit takes place (i) on a regular basis as defined by the Service, unless you give MondoTalk written notice of termination as set forth below; (ii) when the account balance is below a threshold set forth in the Dial Plan Details.
3. EMERGENCY SERVICES – 000 Access
MondoTalk is unable to pass your location details to emergency services, and therefore does not currently offer service to Emergency 000 calls. Please ensure you have a mobile or PSTN line available for your emergency calling needs.
4. Service Distinctions.
You acknowledge and understand that the Service is not intended as a basic telephone Service replacement. Important distinctions (some, but not necessarily all, of which are described in this Agreement) exist between telephone Service and the enhanced VoIP Service offering provided by MondoTalk. The Service is subject to different regulatory treatment than telephone Service.
This Service is not a local telephone Service or a regular long-distance telephone Service. This treatment may limit or otherwise affect your rights of redress before applicable Australian regulators such as the Australian Communications and Media Authority (ACMA) and the Telecommunications Industry Ombudsman (TIO).
5. Service Outage
Power Failure or Disruption.
You acknowledge and understand that MondoTalk Service does not function in the event of a power failure or disruption. Should there be an interruption in the power supply, the Service will not function until power is restored. A power failure or disruption may require the Customer to reset or reconfigure Equipment prior to utilizing the Service.
Broadband Service / ISP Outage or Termination / Suspension or Termination by MondoTalk
You acknowledge and understand that Service outages or suspension or termination of Service by Your broadband provider and/or ISP or by MondoTalk will prevent ALL Service, but You will continue to be billed for the Service unless and until You terminate Service in accordance with this Agreement. You acknowledge that MondoTalk out-sources the actual Internet telecommunications Voice over Internet switching infrastructure, and You acknowledge that MondoTalk will not be liable for any interruptions of Service, failure of Service or termination of Service.
Service Outage Due to Suspension of Your Account.
You acknowledge and understand that Service outages due to suspension of Your account as a result of billing issues will prevent ALL Service.
6. Pay-Per-Call Services
MondoTalk will not directly complete any calls to 1-900, 1-976 or other pay-per-call Service.
7. Phone number
The phone number we assign to You is not Your property. We may assign the phone number to another Customer if You cancel Service, Your account becomes an Inactive Account (including closure for inactivity under clause 14.1), or Service is terminated under this Agreement, or for technical reasons.
There is no minimum period of time that the number will remain idle. We reserve the right to reassign the number any time after the number becomes available. We may have to assign You a different number during the term of this Agreement, but we will notify You in advance.
8. Number Portability and Service Numbers
8.1 Keeping your existing number (Local Number Portability).
You may be able to port your existing fixed-line or mobile number to your MondoTalk Service. Local Number Portability is subject to carrier capability, your current provider’s requirements and applicable law. We may require an authorisation and supporting details from you to initiate a port. Downtime during a port is typically minimal but is not guaranteed.
8.2 Purchasing numbers from MondoTalk.
You may purchase telephone numbers from MondoTalk separately. Because this is an internet-based voice service, calling patterns are not tied to traditional geographic area codes and your Service will ring wherever you connect compatible equipment or apps to the internet, subject to our Service terms.
8.3 Number ownership and changes.
Numbers are allocated and managed under Section 7 (Phone number). We may need to change or reclaim a number in accordance with that section (including where your account is closed for inactivity under Section 14.1).
9. Payments and Billing.
You authorize MondoTalk to use Automatic Debit for charges incurred from the use of MondoTalk Services. As long as your credit card remains valid and in good standing, You may continue to use MondoTalk Services. You agree to pay for all charges incurred by the use of MondoTalk Services made available to You. You agree to comply with all other terms and conditions set forth in this Agreement.

You are not authorized to use your MondoTalk Services after your account has expired, or terminated. You remain responsible to MondoTalk for any charges resulting from the use of your MondoTalk account after any such an event. Charges are immediately payable to MondoTalk.
Calls are billed in one-minute increments, with a minimum time per call of one minute. Billing for calls begins when you press the “send” or “talk” button, and ends when you hit the end key or both parties disconnect. All rates are subject to change without prior notice.
All calls made to mobile telephones are deemed to have been completed. Forwarded calls from the system to any external numbers are deemed as outgoing calls and regular rates will apply. You must notify MondoTalk in writing of any disputed charges within thirty (30) days of the charges or you will be deemed to have waived your right to dispute the charges.
We will use commercially reasonable efforts to notify you of any changes to services charged using Automatic Debits, such notification are not considered a prerequisite to the effectiveness of any such change. Rates do not include additional charges you may incur for originating a call from a cell phone.
You will be responsible for any taxes which are or may come into effect for the Services offered. These taxes will be deducted using Automatic Debits or charged directly to your pre paid card.
All recurring fees and any additional per minute charges incurred will be deducted using Automatic Debits.
