Hi!
Maybe there is a fragmentation... if I make a dump of "normal" phone calls, the "INVITE" package also has 54 Bytes (but the difference is that there is protocol=SIP in the ethereal).
What is IOS? :-S
Thanks!

Strange. There is only 54 bytes of UDP data although the UDP header says there are 1212 bytes of payload.
Is there fragmentation?
Do you use the newest IOS?

Most likely Cisco is sending you a malformed request. Try to fix the
problem
on the Cisco side. Maybe you can send the dump to the list and we can
help
identify the problem.
