Prefix Dialing - Aastra 9000i Series Administrator's Manual

Prefix Dialing

The IP phones support a prefix dialing feature for outgoing calls.
You can manually dial a number or dial a number from a list. The phone automatically maps the
pre-configured prepended digit in the configuration, to the outgoing number. When a match is
found, the prepended digits are added to the beginning of the dial string and the call is dialed.
You can enable this feature by adding a prepend digit(s) to the end of the Local Dial Plan
parameter string in the configuration files or the Aastra Web UI at
Basic Settings->Preferences->General.
For example, if you add a prepend map of "[2-9]XXXXXXXXX,91", the IP phone adds the digits
"91" to any 10-digit number beginning with any digit from 2 to 9 that is dialed out. Other
examples of prepend mappings are:
1X+#,9 (Prepends 9 to any digit string beginning with "1" and terminated with "#".)
•
6XXX,579 (Prepends "579" to any 4-digit string starting with "6".)
•
[4-6]XXXXXX,78 (Prepends "78" to any 7-digit string starting with "4", "5", or "6".)
•
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.
