Objet : RE: [SR-Users] Subst_body M Audio
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,

Hello,
I’m trying to replace the M part in the SDP Body.
Seems not working as expected ( I changed the “s” part without
problems )
Code :
if ( subst_body('/(^m=.*)/m=testing of rewrite.\r/') ) { $var(s)="";
};
Here’s the incoming body message
c=IN IP4 217.112.180.235.
t=0 0.
m=audio 49152 RTP/AVP 8 9 18 101.
a=rtpmap:8 PCMA/8000.
a=rtpmap:9 G722/8000.
a=rtpmap:18 G729/8000.
a=fmtp:18 annexb=no.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
After subst. ( note the .10840 on the m line)
c=IN IP4 217.112.180.10.
t=0 0.
m=testing of rewrite..10840
a=rtpmap:8 PCMA/8000.
a=rtpmap:9 G722/8000.
a=rtpmap:101 telephone-event/8000.
a=fmtp:101 0-15.
a=nortpproxy:yes.
