Comstar has implemented a VoIP network solution from Nortel to help accommodate the need for reliable, affordable long-distance VoIP across the entire Russian Federation. Comstar obtained its long-distance access area codes for Russia in July 2008 and has begun commercial operations of long-distance voice services.

Russia is the largest country in the world spanning more than an eighth of the Earth's land area. In a country of this size, affordable communications - especially long-distance communications - is important to stay connected with friends and family. With the new Carrier VoIP network from Nortel, Comstar can provide affordable, long-distance VoIP across all regions of the Russian Federation including Moscow, St. Petersburg, Novosibirsk, Yekaterinburg, Samara, Rostov-na-Donu, Vladivostok and other regional centres.

Comstar's VoIP network is built on the Nortel Communication Server 2000, an IP multimedia softswitch that delivers network infrastructure services and supports a wide range of voice and multimedia features based on the open, industry-standard SIP protocol. CS 2000 is part of Nortel carrier multimedia network portfolio which also delivers application oriented solutions for carriers such as IP Powered Business serving enterprise and SMB subscribers as well as IP Powered Home serving the residential mass market. According to Dell'Oro Group, Nortel is the worldwide leader in carrier VoIP and has maintained that position for the last six years (2002-2007). Nortel has shipped 88 million carrier IP voice and multimedia ports to approximately 300 carriers globally.
