Configuring Operational Features

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:

An example of a SIP Local Dial Plan is:

[01]XXX|[2-8]XXXX|91XXXXXX
