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.
