Routing Outgoing Calls
Understanding ARS Analysis
Administrator’s Guide for Avaya Communication Manager 219
November 2003
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.
Restricted area codes and prefixes
Certain area code numbers are set aside in the North American Numbering Plan. These numbers are 200,
300, 400, 500, 600, 700, 800, 877, 888, 900. You need to specifically deny calls made to area codes 200
through 900 (except 800 and 888).
You can also deny access to the 976 prefix, which is set aside in each area code for pay-per call services,
if you do not want to incur charges. You can block 976 or any other prefix in all NPAs with a single entry
in the digit analysis table. See
Using wild cards on page 220 for more information.
Instructions
Set the 200 area code apart from other area codes 201 through 209. We use the digit analysis table 120
because it defines long distance calls that begin with 1 and all area codes from 200 through 209.
To deny long distance calls to the 200 area code:
1
Type change ars analysis 120 and press
ENTER
.
The AAR and ARS Digit Analysis Table screen beginning with 120 appears.
The table in our example shows 2 translations for calls that begin with 120.
First, follow the routing for a long-distance call that begins with 120 and is allowed. The 120 translation
handles all dial strings 1-201 through 1-209, and there are many matches.
•
A user dials 9 120 plus 8 digits (the first of the 8 digits is not 0).
•
Communication Manager drops the ARS FAC (9 in our example), looks at the ARS Digit
Analysis Table for 120, and analyzes the number. It determines the call is long-distance and sends
the call over route pattern 4.
Now we will follow a call that begins with the restricted area code 200. Only one string matches this
translation.
•
A user dials 9 1200 plus 7 digits.
•
Communication Manager drops the ARS FAC (9), and looks at the ARS Digit Analysis Table for
1200. It determines that the call type is deny, and the call does not go through.
