Goal - organize the operation of the call center and streamline internal employee communication.
Ensure high-quality and, most importantly, reliable connectivity.
Optimize costs and resource usage.
With Mamonty, the company implemented regional virtual phone numbers and outbound call services. The organization chose to connect via a SIP trunk using a physical connection.
According to corporate policy and internal IT security standards, the company is permitted to connect telephony services from external providers at the boundary between its corporate IP network and internal phone system.
As a result, the client’s equipment was connected to Mamonty’s network in the data center. Through this dedicated VPN channel (with guaranteed quality), the company successfully integrated all required telephony services into its internal network.

Autogenerated outbound calls and call-center manager calls were going through the same routing path, causing congestion and inconsistent call quality. The majority of outbound traffic was directed to Mexico, where the existing provider offered expensive and unstable routes. Automated dialer traffic impacted the performance of the live call-center system, resulting in delays and dropped calls.



A separate SIP trunk was deployed specifically for human-handled calls, isolating the load and ensuring stable manager outbound traffic.
Mamonty integrated with a direct Tier-1 Mexican carrier, reducing the per-call rate and ensuring more reliable delivery.
Failover routes, quality monitoring, and automated rerouting were added to avoid congestion or carrier filtering.

Question:
What is a SIP Trunk?
Mamonty
Support;
A SIP trunk (Session Initiation Protocol trunk) is a virtual phone line that uses the internet to connect your business phone system to the Public Switched Telephone Network (PSTN). Unlike traditional phone lines, SIP trunks allow you to make and receive calls through your existing internet connection, offering greater flexibility and lower costs.
Question:
How does a SIP Trunk work?
Support;
A SIP trunk works by transmitting voice, video, and data over an IP network. It connects your company’s PBX (Private Branch Exchange) to the internet via SIP protocol. This eliminates the need for physical phone lines and enables seamless global communication between offices, customers, and remote teams.
Question:
Can I use SIP Trunking internationally?
Mamonty
Support;
Yes, absolutely. Our SIP trunking service supports global connectivity in over 100 countries. Whether your business operates in Europe, North America, Asia, or the Middle East, you can use SIP trunks to connect your communication systems worldwide with local numbers and crystal-clear voice quality.
Question:
Is SIP Trunking secure?
Mamonty
Support;
Yes. A professionally managed SIP trunk includes advanced encryption, authentication, and firewall protection to prevent unauthorized access and data breaches. We use industry-standard security protocols to keep your business communications safe and compliant.
Question:
What do I need to set up a SIP Trunk?
Mamonty
Support;
To set up a SIP trunk, you’ll need:
  • A stable internet connection with sufficient bandwidth
  • A SIP-compatible PBX or VoIP gateway
  • SIP trunk credentials from your provider
Our technical team assists with the configuration to ensure smooth integration with your existing system.

Question:
How is SIP Trunking different from VoIP?
mamonty
Support:
While both use internet-based communication, VoIP refers to the technology that enables voice calls over IP, and SIP trunks are the virtual lines that carry those calls. In other words, SIP trunking is the backbone that allows VoIP to scale for business use.
Question:
Do you support SIP or H.323?
mamonty
Support:
We support both.
