[asterisk-users] pcapsipdump or general sip debug question

[Yves]

Hi,

I am using pcapsipdump for debugging sip calls.

when I have to debug a call, pcapsipdump generates two files per call... 
one for the sip dialog between the client (softphone) and the server 
(asterisk) and one
for the sip dialog between the server (asterisk) and the sip 
registrar... is there a way to get this into one file ? the objective is 
to see both sides of the call in
a single ladder diagram or just to have more comfort in analyzing the 
full flow within wireshark.

If this is not possible, is there a free tool for sip (together with 
rtp) debugging that is able to catch the full sip flow between both ends 
of one call in a single file
(per call) with pcap compatibility (including the rtp packets)?

thank you
yves
