Hi all, Is there a proper way to use some other media stack (WebRTC in my case) and use pjsip for signaling? I already have webrtc up and running in my android/ios app and need this just for signaling. For example, when i want to create a call I would pass the SDP from webrtc and want that to be sent to the peer, who would in his case extract the SDP and again pass it to the webrtc to handle the media. I implemented this with sip instant messages and my custom logic, but I would prefer to use proper sip way and to use transactions so server can properly handle the call. I found something here (https://trac.pjsip.org/repos/wiki/3rd_Party_Media_20) but I am not rally sure how I would incorporate this behavior in that API. Any help is welcomed. Best regards, Marko
