Hi,
Has anyone made a
tool for RTP listening/snooping? Along the lines of a Sage 930A but
for
SIP/RTP. I have had a few situations where we see traffic
passing both ways but only get audio
in one
direction. Most likely sending silence? It does not help
when the vendors point fingers at each
other. It would also help when looking for audio
quality problems.
What I had in
mind was taking something like tcpdump and splicing it with the RTP portion
of
a
softphone. I actually started something along these lines, but did
not have the time to complete
it. I also
considered creating a proxy with a 1 to 1 transcoder, but that would introduce
another
variable into the
system I am trying to troubleshoot, which I did not want to
do.
Thanks,
Carl.
