Hi!
I just made two tcpdumps with the parameter -s (-s 0 and -s 1024) and
ethereal showed me the same result.
So I think you have the complete dump. Does anyone know how to setup cisco
signalling or something like that? The problem is that the Cisco is of
another company (I want to make an inbound)... it would be nice to give them
a hint.
Thanks!
Sebastian

MAy it be that you make the dump with tcpdump, and
display it with
ethereal?
tcpdump usually only captures not the whole package. Try to capture the
whole packet, e.g
tcpdump -s 0 ......
Just because ethereal can't decode the SIP message does not mean that it
is not a valid SIP message. But therefore we need a complete dump to
analyze the problem.
