Address Maps
In general, address maps should be used for cases that are not covered by the dialplan. Possible scenarios are:
• set the calling number to that of the central office on SIP-to-PSTN calls,
• change the called extension to another value if an employee left,
• remove trunk prefixes while routing to a global voicemail server.
Each address map consists of a number of rules that are checked and applied from first to last until a matching
rule is found that has the
Stop on match option enabled. A rule matches only if all three expressions of that
rule match. The order of the address maps is not important, but the order of the rules within a map is significant
and can therefore be changed with the "arrow down" and "arrow up" buttons.
To add an address mapping, click the Add button. To change the settings for each address mapping, click the
Details button on the right hand side. To open the online help for a specific parameter, click the parameter and
a window with the help text pops up.
You may configure the parameters shown in the graphic and explained below:
Address map name: Enter a name for the address map that helps you remember the purpose of the map. This
name is shown in other menus where an address map may be selected.
Note: The name may be edited only during the creation of a map.
Rule name: Enter a name for the rule of the map, e.g., "Remove 9 from all incoming calls".
