Summary:                    [patch] CANCEL gets different via header branch than
INVITE
Description: 
Asterisk 1.4 sends one branch in INVITE and one in CANCEL. THis is not
compliant with RFC 3261, that says clearly that the cancel needs the same
branch.

Use the same branch tag in CANCEL as in INVITE

Originally putnopvut implemented some changes in revision 142079 that
according to the bug report seemed to have worked then, but somehow fails
now.
I guess code, as humans, get old and forget stuff. Anyway, this bug caused
CANCEL not to work with picky systems. 

Thanks Fredrik for pointing out where the bug in the SIP messaging was.
