9 DIAL STRINGS
The dial plan specifies the sequence of key-presses that may be entered by the user via
the SDP660 to initiate connectivity to a remote party using another terminal in the
network. Additionally, dial strings may be entered to alter a terminal’s behaviour or
configuration without initiating a call.
Dial strings may be entered via the keypad or stored in the contacts lists.
