i made a test where invite has

  m=audio 50152 UDP/TLS/RTP/SAVP 96 97 8 0 101

and i call rtpengine_offer on it like this:

  rtpengine_offer(ICE=force replace-session-connection replace-origin via-branch=1 RTP/AVP trust-address)

and on 200 OK from callee which has

  m=audio 50162 RTP/AVP 96 97 8 0 101

i call rtpengine_answer like this:

  rtpengine_answer(ICE=force UDP/TLS/RTP/SAVP via-branch=2 trust-address)

rtpengine complains about it:

  Nov 17 15:07:32 rautu rtpengine[29718]: Unknown flag encountered: 'UDP/TLS/RTP/SAVP'

but still it has converted m line of the 200 OK to caller to this:

  m=audio 50180 UDP/TLS/RTP/SAVP 96 97 8 0 101

and audio works fine between the RTP/AVP UA (sems) and UDP/TLS/RTP/SAVP
UA (baresip).

why the unknown flag message?
