SIP Trunk
Servises

An international SIP trunk is

a virtual multi-channel communication line that enables companies to make and receive international calls over the Internet using the SIP (Session Initiation Protocol). This technology connects a company’s PBX system with the internet provider’s network, allowing voice and video communication without the need for traditional telephone wiring.
Types of SIP Trunk Services:
  • Standard SIP Trunk

    Helps reduce call expenses and streamline communication processes, even when using budget-friendly SIP providers.
  • Advanced SIP Trunk

    Offers detailed analytics, strengthened security, and support for complex call scenarios — a perfect choice for businesses planning to purchase SIP services online.

Connecting multiple office locations into one unified phone system via a reliable SIP trunk provider.

Businesses that need smooth integration with CRM platforms or other internal systems.

Organizations aiming to cut communication expenses with cost-effective SIP trunk solutions.

Companies expanding into international markets and seeking affordable SIP providers.

Handling large call volumes in call centers.

Online Gambling Case

Our client did not have a local presence in the Philippines, which made it impossible to establish a direct connection without our assistance.
Before reaching out to us, they had only relied on temporary, costly, and low-quality solutions.
Because the client had to share communication lines with other users, the ASR* (Answered Seizure Ratio) — the percentage of successfully connected calls — remained low.

Results:
This time, our client wanted to enter the Philippines. They chose bulk calls as their primary traffic generation channel. Bulk calls are fast, allowing them to reach their target audience and generate interest.
"Special thanks to managers, for prompt communication at any time. We tested about 20 routes and chose the ideal one for our traffic. I wish your team development!"

It is possible thanks to direct cooperation with the direct VoIP providers and operators.
These providers give us large amounts of direct routes, so we can guarantee a high quality connection.
We took into consideration all the client's requirements and set the routing on the day of the request.
Thanks to our approach of building routing that includes several verified providers and backup routes, we are able to increase and maintain a stable number of ports, which directly contributes to a higher rate of successful calls.
Our client was highly satisfied with the quality of service and the performance of the route and has since submitted a new request for an additional direction — a VoIP channel to the Philippines.
Currently, the client operates 10 active trunks with a daily traffic volume of 50,000 minutes.

IT-Corporation

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.
Since the company's equipment is physically located in one of the central regions of Brazil, this allowed the company to integrate directly into our network infrastructure via a dedicated connection.
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.

The company now operates with two independent VPN channels, over which the SIP trunk and Mamonty telephony services are connected. This setup significantly reduced the risk of service disruptions, failures, or downtime.

Online Betting Case

"Vic&Win" worked with a client base in the Netherlands, but used traditional marketing channels. There was also a problem with tracking the effectiveness of advertising campaigns, which made it impossible to accurately measure ROI. "Vic&Win" team decided to test the hypothesis and remind clients about themselves by sending bonuses via SMS.
A special route for SMS mailings was created, which took into account the specifics of the local market and allowed to optimize the cost of delivery and increase conversion.
SMS mailings were integrated with the online betting platform "Vic&Win" to automate processes and track results.
To activate clients, a chain of SMS messages with individual offers was used, aimed at increasing their involvement in the game process.
