Antratel brought to life a new technology - access to VOIP EXCHANGE. Now, Antratel customers have access to VOIP EXCHANGE and can choose personally right price and quality for calls termination from thousands offers of telecom companies!

There is a global VoIP Exchange where telecom providers can sell call connection (termination) services. Each telecom provider has his own gate (physical socket for making a call), call connection (termination) price and call quality which depends on gate parameters. When you call , for example from Moscow to St. Petersburg, you purchase the termination service from a telecom provider . During initiation of a call, the system enumerates gates (every gate has 30 and more PSTN lines). If the first gate is busy then the system takes the next one. The call order is a sequence of gates through which the system tries to make a call. The sequence is generated by the conditions of the gates parameters. Generally, the system makes a connection by picking the lowest connection price from the exchange.
