(3XXX) so that the call can route correctly through the main office VoIP
trunk. Users registered at the main office dial the main office DN (3XXX) for
the SRG IP Phone.

In Local mode, the users registered to the SRG still dial the SRG IP Phone
DN (4XXX). The main office users can not call the SRG IP Phone by dialing
the main office DN for the telephone (3XXX) because the NRS cannot route
the call to the SRG. If the main office user dials the SRG IP Phone DN
(4XXX), the call goes through.
