Local Dial Plan - Aastra 6730i Administrator's Manual

Local Dial Plan

A dial plan describes the number and pattern of digits that a user dials to reach a particular telephone number. Access
codes, area codes, specialized codes, and combinations of the number of digits dialed are all part of a dial plan. For
instance, the North American Public Switched Telephone Network (PSTN) uses a 10-digit dial plan that includes a 3-digit
area code and a 7-digit telephone number. Most PBXs support variable length dial plans that use 3 to 11 digits. Dial plans
must comply with the telephone networks to which they connect. Only totally private voice networks that are not linked
to the PSTN or to other PBXs can use any dial plan.
The Dial Plan field accepts up to 512 characters. If a User enters a dial plan longer than 512 characters, or a parsing error
occurs, the phone uses the default dial plan of "x+#|xx+*". You configure the SIP Local Dial Plan using the Aastra Web UI or
the configuration files.
The IP phone SIP local dial plan available symbols are as follows:
Symbol
0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Dial Plan Example
An example of a SIP Local Dial Plan is:
[01]XXX|[2-8]XXXX|91XXXXXX
XXXX|X+.|*XX
The dial plan in the above example can accept any 4-digit dial strings that begin with a '0' or '1' , any 5-digit dial strings that
begin with a '2' up to '8' , any 12-digit dial strings that begin with '91' , any non-empty digit string that ends with a ' . ' or any 2-
digit code that begins with a '*' .
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 pre-
pended 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.
Note:
The prepend digits are also added if the dialing times-out on a partial match.
You can enable this feature by adding a prepend digit(s) to the end of the Local Dial Plan parameter string in the configu-
ration files or the Aastra Web UI at
Basic Settings->Preferences->General.
