Examples of Digit Conversion

Last Updated : Oct 08, 2020 |

Purpose

Your system uses the AAR or ARS Digit Conversion Table to change a dialed number for more efficient routing. Digits can be inserted or deleted from the dialed number. For instance, you can tell Communication Manager to delete a 1 and an area code on calls to one of your locations, and avoid long-distance charges by routing the call over your private network.

ARS digit conversion examples

The ARS digit conversion table reflects these values:

  • ARS feature access code = 9

  • AAR feature access code = 8

  • Private Network Office Code (also known as Home RNX) = 222

  • Prefix 1 is required on all long-distance DDD calls

  • Dashes (-) are for readability only

Communication Manager maps the dialed digits to the matching pattern that most closely matches the dialed number.

Example:

If the dialed string is 957-1234 and matching patterns 957-1 and 957-123 are in the table, the match is on pattern 957-123.
