[sr-dev] rtpengine SDP duplication

[Alex Balashov]

Hello,

I am not calling rtpproxy_offer() from branch_route (though perhaps I 
should be), but rather from a request route called from a failure_route. 
However, rtpproxy_offer() does get called every time on every branch, 
and perhaps that is the route of my mistake.

I'll investigate more and see what I can figure out. It seems to me that 
the aim should be to call rtpproxy_offer() from branch_route and have it 
work precisely as Juha expects, because I need to have the option of 
hairpinning media on some branches and not on others.
