Mediant 800B Gateway & E-SBC
The following procedure provides a summary on how to create a Dial Plan file and select
the required Dial Plan index.
To configure a dial plan:
1. Create a new file using a text-based editor (such as Notepad) and configure your Dial
Plans, as required.
2. Save the file with the ini file extension name (e.g., mydialplans.ini).
3. Convert the ini file to a dat binary file, using AudioCodes DConvert utility. For more
information, refer to DConvert Utility User's Guide.
4. Install the converted file on the device, as described in 'Loading Auxiliary Files' on
page 831.
5. Select the Dial Plans you want to use and configure a digit map:
a. Open the DTMF & Dialing page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > DTMF & Dialing).
b. In the 'Dial Plan Index' field, enter the Dial Plans by index number that you want
to use. The parameter can be set to 0 through 7, where 0 denotes PLAN1, 1
denotes PLAN2, and so on.
c. In the 'Digit Mapping Rules' field, enter the digit map.

6. Click Apply.
Note:
• The Dial Plan file must not contain overlapping prefixes. Attempting to process an
overlapping configuration by the DConvert utility results in an error message
specifying the problematic line.
• The Dial Plan index can be selected globally for all calls (as described in the
previous procedure), or per specific calls using Tel Profiles.
• 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 file) 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 configure digit patterns that are shorter than those
defined in the Dial Plan or left at default (MaxDigits parameter). For example, the
“xx.T” digit map instructs the device to use the Dial Plan and if no matching digit
pattern is found, 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.
• By default, if no matching digit pattern is found in both the Dial Plan and Digit Map,
the device rejects the call. However, if you set the DisableStrictDialPlan parameter
to 1, the device attempts to complete the call using the MaxDigits and
TimeBetweenDigits parameters. In such a setup, it collects the number of digits
configured by the MaxDigits parameters. If more digits are received, it ignores the
settings of the parameter and collects the digits until the inter-digit timeout
configured by the TimeBetweenDigits parameter is exceeded.
