Telephony

Yate is a telephony engine who's main function is to connect together call legs to external devices or to internal server resources and for that he use a variety of VoIP protocols that can be used without the need of a special hardware as SIP, H.323, IAX2 or Jingle. In the next chapters you will find more informations about configuring each telephony protocol and the features supported by Yate.

Session Initiation Protocol (SIP)

The SIP module in Yate allows you to make calls using SIP protocol.
