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 '*'. 

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”.)

The prepend digits are also added if the dialing times-out on a 

partial match.

You can configure a local dial plan via the configuration files or 

the Aastra Web UI.
