[SR-Users] Subst_body M Audio

[Nicolas Breuer]

Replace_body works .

replace_body("AVP 8 9", "AVP 9 8");

Before
m=audio 49152 RTP/AVP 8 9 18 101.
a=rtpmap:8 PCMA/8000.
a=rtpmap:9 G722/8000.
a=rtpmap:18 G729/8000.


After
m=audio 17782 RTP/AVP 9 8 101.
a=rtpmap:8 PCMA/8000.
a=rtpmap:9 G722/8000.

Hello,

I tried to disable the rtpproxy & indeed the issue is not present.

I put the subst_body at the end of the script ( in the branch_route section ) Rtpproxy is called before and the sdp body is still altered

m=audio 49152 RTP/AVP 9 8 101.11648
a=rtpmap:8 PCMA/8000.
a=rtpmap:9 G722/8000.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
a=nortpproxy:yes.

Hi,

it seems you are triggering RTPProxy after the subst_body (hence the port and the parameter a=nortpproxy in the SDP).

Try removing RTPProxy.

Thanks,
Carsten
