[SR-Users] Different rtpproxy for different media type

[Koray Vatansever]

I think I couldn't explain myself clearly.
I want to see the following media lines in resulting SDP:

m=audio 10076 RTP/AVP 97 98
c=IN IP4 rtpproxy1.example.com
a=rtpmap:97 speex/8000
a=fmtp:97 vbr=on
a=rtpmap:98 telephone-event/8000
m=video 20007 RTP/AVP 96
c=IN IP4 rtpproxy2.example.com
a=rtpmap:96 VP8/90000
