Routing Outgoing Calls
Understanding ARS Analysis
Let us say a caller places a call to 1-303-233-1000. Communication Manager matches the dialed digits
with those in the first column of the table. In this example, the dialed string matches the '1'. Then
Communication Manager matches the length of the entire dialed string (11 digits) to the minimum and
maximum length columns. In our example, the 11-digit call that started with 1 follows route pattern 30 as
an fnpa call.
Tip:
The first dialed digit for an external call is often an access code. If '9' is defined as the
ARS access code, Communication Manager drops this digit and analyzes the remaining
digits with the ARS Analysis Table.
The Route Pattern points to the route that handles the calls that match this dial string.
Call Type tells what kind of call is made with this dial string. Call type helps Communication Manager
decide how to handle the dialed string.
Examples of digit conversion
Your system uses the AAR or ARS Digit Conversion Table to change a dialed number for more efficient
routing. Digits may 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.
The table below 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.
