Largest Russian IP telephony provider selects CommuniGate Systems to build advanced next-generation VoIP network

CommuniGate Pro enables Tario Communications to launch new services and support growing VoIP adoption.

MILL VALLEY, CA (April 18, 2006) - CommuniGate Systems, the leader in scalable carrier-class Internet Communications solutions, today announced that Tario Communications, the largest VoIP carrier across Russia, has implemented the CommuniGate Pro Internet Communications platform to provide comprehensive security, scalability and reliability for Tario's extensive voice and data network.

Serving more than 300,000 customers and hosting over 60 million minutes of phone calls and messages each month, Tario needed to upgrade its internally-built network to meet growing demand. In order to build a sustainable next-generation VoIP network, the carrier was looking for a single, standards-based platform that would offer high performance, strong technical support and room to grow as the subscriber base increased. Tario additionally wanted near-flawless uptime and seamless upgrades to maintain high levels of customer satisfaction.

After reviewing multiple systems, Tario selected CommuniGate Pro Dynamic Cluster with SIP Farm. As CommuniGate Pro's patent-pending technology for clustering VoIP, SIP Farm provides 99.999% uptime, redundancy and scalability. Tario can now allocate subscribers and telephony class of service to the SIP Farm based on traffic or regional geographic placement. CommuniGate also provides the infrastructure and functionality for SIP trunking, as well as standards-based email messaging. Tario now receives outstanding performance and interconnectivity between different vendors for various applications.

"As our VoIP subscriber base dramatically increased, it became clear that we needed to install a scalable solution that was easy to implement and interoperable with our existing infrastructure," said German Myzovsky, director of network development at Tario Communications. "Offered as a single platform to handle all our IP Communications traffic, including Webmail, POP and VoIP, CommuniGate Pro was a perfect fit for our needs. Tario is now assured its customers will receive reliable, secure services, enabling us to concentrate on building new value-add features."

"As the leader in the Russian VoIP industry, Tario needed a solution that not only focused on email security and performance, but also outstanding VoIP capabilities. With the easy-to-use CommuniGate Programming Language [CG/PL] Tario is able to quickly roll out new IMS applications," said Jon Doyle, vice president of business development for CommuniGate Systems. "CommuniGate Pro provides carriers like Tario with the increased flexibility they need to grow, all on a multi-node cluster that behaves as a single system and scales over time."

CommuniGate Pro v5.0 allows subscribers a choice of clients - IP phones, soft clients, traditional telephony, mobile devices, browsers and IM agents - all through a single account. Traditional telephone numbers are available through PSTN connectivity and ENUM, while CommuniGate Pro 5.0 integrates with IMS media and content through CommuniGate Programming Language (CG/PL) and published APIs, and handles signalling and media for multiple gateways for IP-to-IP, PSTN-to-IP and PSTN-to-PSTN connectivity. Ultimately, CommuniGate Pro 5.0 provides a single source for email, collaboration, voice/video and mobile Internet Communications.
