Yate as a Conference Server
From Yate Documentation
Yate can be used as a Conference Server in two ways:
- you can execute a conference directly from routing module (e.g regexroute.conf),
- or you can do it programmatically using call.conference message from an external script or by using module Pbxassist, that has the capability of doing PBX operations for conference on receiving DTMF sequences.
