Answer 1

Hi,
The problem mght be at both ends.
To: "u0" <sip:user@rip:44284>
From: "0" <sip:user@lip:16402>;tag=297873739
Call-ID: 7b6c5d44-f6d3-11dc-875a-9ce2eb7c4012@lip
CSeq: 1 INVITE
Contact: <sip:user@sip:56359>;isfocus
The bit with rip is the far end.
The lip is the end this log came from.
The lip was the caller, the one doing the invite.
The sip bit lower down and the rip bit both have port numbers that are not used by iChat.
Can you tell us what make and models of modem and router you have and any info on what you know they do or have been set up to do ?
