[SR-Users] webrtc clients support using rtpengine

[Andrey Utkin]

This works: call from sipml to linphone android:

ngrep: https://gist.github.com/krieger-od/cb5829be7a55a7acf9d3


This doesn't work: few seconds after answer, there's no media from
remote subscriber, then linphone android agent hangs up; sipml hangs
pretending being in call.
