[SR-Users] rtpengine rewrite sdp for second time

[Carsten Bock]

Hi Virmantas,

you could try to one or a combination of the following:
- explicitly delete the first session by calling rtpengine_manage() in
the failure route
- call msg_apply_changes() from Textops before calling
rtpengine_manage() the second time (so the already made changes are
applied and the message gets reparsed)

Thanks,
Carsten
