NAT support for SIP Fragmentation ????

Unanswered Question
Nov 5th, 2007

Hi, I have seen a doc that talks about NAT support for SCCP fragmentation, but cant seem to find anything for SIP.

My problems is that when SIP packets are TCP fragmented, the ALG on my 2811 does not seem to re-assemble the SIP message correctly.

The IOS version is 12.4(3e)

It seems to re-construct the message by truncating parts, which causes my SIP application to fail.

Any ideas / comments ??

I have this problem too.

your best action would be first to upgrade to 12.4(11)XJ4 that has the most bug fixes and advanced features. if the problem still occur, please send config and how do you infer that fragmented SIP in TCP cannot be reassembled.
