Does PJSIP support RFC 6849 "An Extension to the Session Description Protocol and Real-time Transport for Media Loopback"? I'd like to create a loopback session between a PJSIP based software agent and a Sip phone (Cisco) that supports this capability. If PJSIP doesn't do this, does anyone know if RFC 6849 is on the roadmap?
