Defining Inter-exchange carrier calls

Last Updated : Aug 11, 2014 |

About this task

Here is an example of how Communication Manager routes an ARS call to an inter-exchange (long-distance) carrier (IXC). IXC numbers directly access your long-distance carrier lines. IXC numbers begin with 1010, followed by three digits, plus the number as it is normally dialed including 0, 00, or 1+ 10 digits. These numbers are set up on your default translations. Remember, the user dials 9 to access ARS, then the rest of the number.

Procedure

  1. Type display ars analysis 1.
  2. Press Enter to view the ARS Digit Analysis Table screen starting with 1.

    This table shows five translations for IXC calls.

    When you use x in the Dialed String field, Communication Manager recognizes x as a wildcard. The x represents any digit, 0 - 9. If I dial 1010, the next 3 digits will always match the x wild cards in the dialed string.

    Use the ARS digit analysis table shown above and follow the routing for an IXC call to AT&T. 1010288 is the carrier access code for AT&T.

    • A user dials 9 1010288 plus a public network number.

    • Communication Manager drops the ARS FAC (9 in our example), looks at the ARS Digit Analysis Table for 1010, and analyzes the number.

    • Then it matches 288 with xxx and sends the call over route pattern 5.
