Hello,

there should be a function to remove a line from sdp by matching on its prefix (in sdpops?!?), might be easier to use that one.

Cheers,
Daniel

Hello!

There is a task to remove a fragment (a=rtpmap:8 PCMA/8000#015#012) from the SDP string generated by the rtpengine.

v=0#015#012o=kw 1614043485 1614043486 IN IP4 185.19.237.77#015#012s=kw#015#012c=IN IP4 1.1.1.1#015#012t=0 0#015#012m=audio 31828 RTP/AVP 0 8 101#015#012a=silenceSupp:off - - - -#015#012a=direction:both#015#012a=rtpmap:0 PCMU/8000#015#012a=rtpmap:8 PCMA/8000#015#012a=rtpmap:101 telephone-event/8000#015#012a=fmtp:101 0-16#015#012a=sendrecv#015#012a=rtcp:31829#015#012a=ptime:20#015#012

The most logical option seems to be using the re.subst transformation, but so far no success.

$avp(write_sdp_pv) = $(avp(write_sdp_pv){re.subst,/a=rtpmap:8 PCMA\/8000%23015%23012//s});

Сan there be an alternative or am I doing something wrong with the re.subst?
