Overview This section provides an overview of dialing plan programming on the SRG
and the main office.
When a number is dialed, the Call Server determines whether the called
number is internal or external to the branch office. If internal or off-net, the
system terminates the call on the appropriate terminal. If external or on-net,
the system routes the call using one of the supported dialing plans.
