Dial Plan
Description
Parameter
Dial plan script for the selected extension.
The dial plan syntax allows the designation of three
parameters for use with a specific gateway:
• uid – The authentication user-id
• pwd – The authentication password
• nat – If this parameter is present, use NAT
mapping.
Separate each parameter with a semi-colon (;).
Dial Plan
Inbound caller ID numbers can be mapped to a
different string. For example, a number that begins
with +44xxxxxx can be mapped to 0xxxxxx. This
feature has the same syntax as the Dial Plan parameter.
With this parameter, you can specify how to map a
caller ID number for display on screen and recorded
into call logs.
Caller ID Map
Enables or disables URI dialing.
Enable URI Dialing
Enter a comma-separated list of emergency numbers.
When one of these numbers is dialed, the unit disables
processing of CONF, HOLD, and other similar
softkeys or buttons to avoid accidentally putting the
current call on hold. The phone also disables hook
flash event handling.
Only the far end can terminate an emergency call. The
phone is restored to normalcy after the call is
terminated and the receiver is back on-hook.
Maximum number length is 63 characters. Defaults
to blank (no emergency number).
