A telephone service that allows you to order a connection to the desired subscriber in such a way that the call is incoming for both. Typically, this method is used for international calls through a third country, usually USA, where the call rates are significantly lower than in many other countries. Used by some Internet providers, in those cities where outgoing calls are charged. It works as follows: your modem dials to the provider, negotiates with him about the return call and hangs up, after a while the ISP modem dials in to you and your modem automatically picks up the handset. Thus for you the incoming call and you do not pay for the telephone connection.

Provides voice and multimedia content (video and audio conference, instant messages, online games). This is a fairly simple protocol that provides speed, but does not guarantee the passage of the signal.
