[SR-Users] UAC changing port for same registration

[Sergiu Pojoga]

Are you supporting a single Contact per AoR? Otherwise, I don't see how you
can keep track of "changes in location and detect if an agent is online".

If so, just set the *0x04 *registrar flag and you'll always have the latest
registered Contact address in Location.
