You can configure digit maps for the phone. This configuration completely replaces the use of the DIALPLAN parameter and Enhanced Local Dialing (ELD) to provide both a dial plan and dialing rules at the same time.
Using this feature, you can enable the following:
-
Matching rules which trigger a matching dial plan
-
Substitution rules to provide the same functions as ELD, such as prefix insertion and removal, addition of area codes and country codes.
This feature also enables the phone to block certain numbers from being dialed by users.
You can configure digital maps through the 46xxsettings.txt file with the help of SET and ADD operators, which allows to use several digit maps. There is no set limit to the quantity of rules in a single digit map string, but a character limit of 255 characters for each string in a parameter value applies. You can also configure this feature using the web interface, which is the preferred way of configuration.
A digit map is a group of one or several rules, separated by commas (,). You can use blank spaces in digit maps for better readability, the phone ignores them when reading a digit map.
If a user dials a sequence that matches two or more rules in a digit map, the phone uses the exactly or most closely matching rule for that sequence.
