I found some time to look over the logs you sent to me. The cancel is 
for first branch, not the second. Can you send a sip trace to properly 
confirm that and see if something wrong there? From the logs:

As you can see the branch parameter for cancel ends in .0, while the 
forwarded invite has .1

Cheers,
