that means the invite is not matching the call dialog
compare the via tags and call-id etc

We have a customer that we are sending calls to off the FS and here is the issue:
>Call is initially setup fine and they send a first re-invite with media 0.0.0.0 to place the caller on hold. FS sends a 200 ok to this first re-invite fine
>They then send a second re-invite with their media IP to cut through media and the FS sends a 200 OK to this fine. At this point the call is fine
>30 minutes later they send a third re-invite because according to them it is strictly for the purpose of “keep alive” per RFC 4028. This third re-invite has the exact same media IP and UDP pot information as the second re-invite does. The problem is FS does not respond to this third re-invite AT ALL. It doesn’t send a 100 trying a 200 OK nothing so this causes the call to be dropped as the other end does not recieve a response from FS.
>One more thing, we did not see the third re-invite in sofia siptrace, but we do see it in ethereal, which is kind of odds.
