Operational IP Phone Features
Example
If you enter the following dial string for a local dial plan:
sip dial plan: 1+#,9
where “9” is the prepended digit, and you dial the following number:
15551212
the IP phone automatically adds the “9” digit to the beginning of the dialed
number before the number is forwarded as 915551212.
SIP Dial Plan Terminator
The IP phone allows you to enable or disable the use of the “dial plan terminator”.
When you configure the phone’s dial plan to use a dial plan terminator or timeout
(such as the pound symbol (#)) the phone waits 4 or 5 seconds after you pick up
the handset or after you finish dialing the numbers on the keypad before making
the call.
You can enable or disable the dial plan terminator using Aastra Web UI or the
configuration files.
Digit Timeout
The IP phone allows you to configure a “Digit Timeout” feature on the IP phone.
The Digit Timeout is the time, in seconds, between consecutive key presses on the
IP phone’s keypad. The default for this parameter is 4 seconds. If you press a key
on the phone and wait 4 seconds before pressing the next key, the key times out
and cancels the digit selection. You must press consecutive keys before the
timeout occurs.
Note: You can configure a local dial plan via the configuration files or
the Aastra Web UI.
