User's Manual 25. Configuring DTMF and Dialing
Version 6.8 411 Mediant 500 E-SBC
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
557 ), the device first attempts to locate a matching digit
pattern in the Dial Plan file, and if not found, then attempts to locate a matching
digit pattern in the Digit Map (configured by 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.
25.1.2 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
556 .
