SIP

— the most popular of today's VoIP protocols, used in most IP phones. From a technical point of view, SIP is responsible for establishing a connection and disconnecting, as well as for some additional service features. It is worth noting that different SIP devices are poorly compatible with these additional features, but there are no problems with the basic capabilities.
