RFC 3261, sections 14.1 (UAC behaviour for modifying sessions), 12.2.1.1 (UAC 
generating new in-dialog request), 8.1.1 (General UAC behaviour, generating new 
out-of-dialog request) and especially 8.1.1.7 (the Via part of 8.1.1).

Basically, the INVITE's a new transaction, so it MUST have a new via-branch.
