Summary:                    Asterisk sends a [slightly] different branch id back
on CANCEL than on INVITE when call times out
Description: 
When asterisk does a DIAL with a timeout of 120 seconds, when the 120
seconds expires and asterisk generates a SIP CANCEL message, the branch
sent back is slightly different from the one it sent in the original
INVITE.  This often results in a 481 No such call response back from the
other party and thus the call doesn't get cancelled properly.

If the DIAL command is set to 110 seconds, asterisk responds with the same
branch on the CANCEL than on the INVITE.
