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

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?
