SIP Dial Plan

Destination Type Choose either Dial IP Address or Destination Name.
Destination Name/IP When a match is detected between the collected digits and the dial string in this SIP dialplan, this IP address is used for SIP negotiations to initiate the call. The name of the destination of the specified dial string.
Dial String String used by the dial plan. Each dial string is represented as digits, wildcards, and regular-expression-like patterns according to the following rules:
  • Digits 0 to 9 are allowed as well as * and #.

  • The character x to indicate a wildcard for 0 or more digits between 0-9.

  • A dial-string character T can be used in the Override Interdigit Timeout parameter value in the SIP dialplan. Examples:

– 0T for the number zero and nothing else.

– 011T for numbers 011 then any number of digits before the interdigit time out.

– 9T for the number 9 and any number of digits before the interdigit time out.

– #T anything followed by a # and an interdigit time out.

  • A digit range can be specified using brackets [ ], as follows:
    [135] means digits 1, 3, or 5.
    1-4] means digits 1, 2, 3, or 4.

  • MGCP-style digit mapping where a period ‘.’ represents any digit and a | character indicates an inclusive OR. Examples:

– .T for any number of digits before the interdigit timeout.

– *x.T | x.T indicates star plus any number of digits followed by the inter-digit timeout or any number of digits followed by the inter-digit timeout.

– *.xT | x.T | [2-9]11 indicates star plus any number of digits followed by the inter-digit timeout or any number of digits followed by the inter-digit timeout. or digits 2 to 9 followed by 11. The [2-9]11 explicit digit matching enables expedited call connections for emergency calls
