Location specific ARS digit analysis
Location based analysis is used before global analysis. Using it we could apply rules that only
apply to calls from survivable extensions at location 11. For example, the pattern below routes
calls prefixed 1908 from location 11 back to the Avaya Aura
®
Session Manager using
Route
Pattern 32 on page 320 when a match occurs.
The change ars analysis location x y command is used to make location specific routing
entries where the x is the location number and the y is the dialed digit string to match on.
However for our example, we want to route any dialing prefixed with 1908, regardless of
location, which we can do in the Global ARS Digit Analysis on page 322.
Global ARS Digit Analysis
For this example we want all outgoing external calls prefixed with 1908 to be routed back to
the Avaya Aura
®
Session Manager, regardless of the location of the survivable extension
making the call.
The change ars analysis y command is used to make global routing entries where the y is
the dialed digit string to match. A match on this table can occur if there is no match on the
ARS
Location Specific ARS Analysis on page 322.
The global ARS table as used in the example configuration is shown below. Long distance
calls, 1 + 10 digits, will match the Dialed String of 1 with 11 digits and select
Route Pattern
3 on page 320.
