[OpenSIPS-Users] RTPProxy duplicated SDP rewriting

[Bogdan-Andrei Iancu]

Hi Seth,

I see - what you actually need to do is enable RTPproxy in a per branch 
manner - in this case you can individually set RTPproxy for each 
separate branch you may have for a call.

So, the idea is to move the place where you do the RTPproxy control - 
instead of doing it in request route (changes here will reflect on all 
future branches),  better do it in branch route (where changes will be 
only for that particular branch).

Regards,
Bogdan
