[OpenSIPS-Users] Mediaproxy not updating with new SDPs

Hi Jeff,

I vaguely remember examples of use_media_proxy/end_media_session in the loose route section, failure routes, etc.  Or maybe I'm confusing it with rtpproxy.  Anyway, are there any examples around of a recommended, basic implementation?  Even general guidelines would be helpful just to make sure I'm on the right track.  For example, would it make sense to run end_media_session followed by a use_media_proxy on a reply route any time an SDP is present to "reset" the dispatcher and relays to the new stream?

Currently I don't have such an example, sorry. Basically you'll need to 
call use_media_proxy for the first invite and reply and then for 
in-dialog invites. You only need to call end_media_session when you want 
the session to end.

Some other notes:
   - You could have a late negotiation (offer in the 200 ok and answer 
in the ack)
   - You could get a 180 or 183 with SDP
   - You may call use_media_proxy with an empty invite and it will just 
do nothing.
   - If using PRACK you could have a 183 with SDP and after a 200 OK 
without SDP. You need to call use_media_proxy in both cases. It's 
harmless to call use_media_proxy with an empty 200 OK. (this was fixed 
in MediaProxy 2.4.3)

Hope it helps.
