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 the configuration of a dial plan terminator. When you
configure the IP phone 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 press
a key to make a call.
You can configure the dial plan terminator using Aastra Web UI or the
configuration files.
Note: You can configure a local dial plan via the configuration files or
the Aastra Web UI.
