The append_branch() itself is not doing any SIP signaling. It is only
creating (internally, as data structure) a new branch for the request
(to a new destination).
The signalling (to all created branches) is done by TM module when you
relay the request out. The forking is a transaction level mechanism and
it is handled by the TM module.
