Modifying call routing
If your system uses ARS Digit Analysis to analyze dialed strings and select the
best route for a call, you must change the digit analysis table to modify call
routing. For example, you’ll need to update this table to add new area codes or to
restrict users from calling specific areas or countries.
Adding a new area code or prefix
A common task for system administrators is to configure their system to recognize
new area codes or prefixes.
When you want to add a new area code or prefix, you look up the settings for the
old area code or prefix and enter the same information for the new one.
Tip:
Use display toll xxx (where xxx is the prefix you want to add) to see if the
new area code or prefix number is set up as a toll call (y) or not. Some users
may not be allowed to dial toll call numbers.
