Notes:
• If you want the device to accept/dial any number, ensure that the digit
map contains the rule "xx.T"; otherwise, dialed numbers not defined in
the digit map are rejected.
• If you are using an external Dial Plan file for dialing plans (see 'Dialing
Plans for Digit Collection' on page 634), the device first attempts to
locate a matching digit pattern in the Dial Plan file, and if not found, then
the DigitMapping parameter).
• It may be useful to configure both Dial Plan file and Digit Maps. For
example, the Digit Map can be used for complex digit patterns (which are
not supported by the Dial Plan) and the Dial Plan can be used for long
lists of relatively simple digit patterns. In addition, as timeout between
digits is not supported by the Dial Plan, the Digit Map can be used to
define digit patterns (MaxDigits parameter) that are shorter than those
defined in the Dial Plan, or left at default. For example, “xx.T” Digit Map
instructs the device to use the Dial Plan and if no matching digit pattern,
it waits for two more digits and then after a timeout (TimeBetweenDigits
parameter), it sends the collected digits. Therefore, this ensures that
calls are not rejected as a result of their digit pattern not been completed
in the Dial Plan.
27.1.2 External Dial Plan File
The device can be loaded with a Dial Plan file with user-defined dialing plans. For more
information, see 'Dial Plan File' on page 633.
