Dial Plan

Dial plans specifies how to interpret digit sequences dialed by the user, and how to convert those

sequences into an outbound dial string. The syntax for dial plan closely resembles the corresponding

syntax specified by MGCP and MEGACO.

The dial plan functionality is regulated by the following configurable parameters:

 Interdigit_Long_Timer---refer to Interdigit_long_timer part for details

 Interdigit_Short_Timer---refer to interdigit long timer part for details

 Dial_plan

Dial plan contains a series of digit sequences, separated by | character. The collection of

sequences are enclosed in parentheses, ( and ).

Defaults to (xxxxxxxxxxxx.)

When a user dials a series of digits, each sequence in the dial plan is tested as a possible match. The

matching sequences form a set of candidate digit sequences. As more digits are entered by the user,

the set of candidates diminishes until only one or none are valid.

Any one of a set of terminating events triggers the AT00 to both accept the user-dialed sequence, and

1 2 ... 26 27 28 29 30 31 32 33 34 35 36 ... 42 43
