libosip for Debian ------------------ SIP (rfc3261) is a signalling protocol that initiates, modifies and terminates multimedia sessions. libosip is implement the transaction layer of the SIP protocol. SIP is a replacement for H323 which is close to MAIL and SMTP for both format and the transport protocol definition. SIP is mainly used by IP telephony applications. Some applications using SIP already exist: partysip a SIP proxy server (registrar and routing server) and linphone, a SIP User Agent (softphone) will allow you to access any other SIP user in the world. libosip can be used to implement any kind of applications that need to establish sessions: ip phones is the best example but it could also be the setup of a game sessions or whatever you want. -- Aymeric MOIZARD , Tue, 16 Apr 2002 11:29:25 +0100
