Abstract

The invention relates to a method for providing Voice over IP (VoIP) in a communication system with a number of terminals operating with VoIP, between which a transmission of voice data according to VoIP or a signalling is achieved, wherein the signalling is achieved using the Computer Supported Telecommunication Application (CSTA) interface standard. Telephone services can be controlled by a computer using the CSTA protocol. As for conventional application, H323 protocol and SIP are used for IP telephony processing of audio/video streams of a conversation. The invention is based on replacing H323 protocol and SIP by a CSTA protocol only when the latter is correspondingly extended.
