Hi Andreas,
AFAIK, this sendrecv is optional (it is assumed by default, if not
present).
What you can try is something like:
subst_body('/^m=(.*)/m=\1\r\na=sendrecv/g');
to add a"sendrecv" line after each `m` line (stream). Still, this may be
pron to errors as you may already have some indication there (like a
sendonly)

Hi,
I am replacing an old hardware SBC with a simple OpenSIPS instance
that basically does a little as possible. So topology hiding, rtpproxy
between the "lan" and public side and a few choice header
manipulations. The one problem I am having is that for some reason the
platform on the "lan" side requires an "a=sendrecv" line in the SDP
body.
All the SDP body manipulations I have found are more of the replace
this part of the body with that new value, while I just want to add a
whole line to the end of the body. The old SBC would add this to each
audio "stream" (not sure of the correct terminology here).
I know this is not 100% kosher, because I can't force all the SDP
bodies to be correct, but this is just a test platform that quickly
needs a solution for the broken hardware. And I would really like to
prevent spending money here. It's been a while since I looked into SDP
manipulation using OpenSIPS.
I am currently testing on an older OpenSIPS 2.x release, but could
upgrade to something more recent when necessary.
Anyone have an idea? Thanks!
