The dial plan applied is dependent on the realm that is assigned for the line (Reg.x.Realm).GE and PE realms use the DialPlanExternal parameter, GP uses the DialPlanPbx parameter, and GI usesthe DialPlanIntercom parameter.The following table shows the syntax for dial plan entries and explains the results.Dial Plan ExamplesThis section provides the default dial plan for external calls and PBX environments. An explanation foreach portion of the dial plan is provided to assist you in understanding the dial plan. Adjustments can bemade to these parameters in the configuration file as needed for your situation.Default External Dial PlanThe external dial plan is defined in the DialPlanExternal parameter. Table 15 on page 82 explains thedefault numeric string by breaking it down into pieces. Each portion of the dial plan is divided by a bar ( | )in the full string:0|911|[2-9]xxxxxx+T2|[2-9]xx[2-9]xxxxxx|[0-1][2-9]xx[2-9]xxxxxx|011xxx+T2Table 14. Dial Plan Syntax EntriesTo Specify Enter ResultDigit 0 1 2 3 4 5 6 7 8 9 0 Identifies a specific digit.Range of Digits [Digit-Digit] OR[Digit-Digit, Digit]Specifies a range that will match a digit.Wildcard x Matches any single digit that is dialed. Matches anyarbitrary number of digits or range of digits, includingnone.Multiple Dial Plans | Specifies more than one dial plan using the | symbolto separate them. For example:911|9xxxxxxx|Timer Tn Indicates an additional time out period (n = secondsin length) before digits are sent. n is mandatory andcan have a value of 0 to 9 seconds. Tn must be thelast 2 characters of a dial plan. If Tn is not specified,it is assumed to be T0 by default on all dial plans.Note: The appropriate DialDelay* parameter mustbe set to 0 (disabled) if these timeout periods areused.
