World Class Routing (DEFINITY ECS and
DEFINITY G2.2 and G3 only)
The World Class Routing (WCR) feature replaces and enhances the AAR/ARS
feature. Specific digit strings are assigned to either allow or deny calls. The 900
look-alike numbers can be routed for interception. The 800 numbers for ICX
carriers can be blocked. This still allows normal 800 numbers to be dialed.
Specific international numbers can also be blocked.
You may also route 0 or 00 calls to a local attendant for handling. In addition,
101xxxx + calls can be restricted. Certain laws and regulations may prevent you
from blocking these calls, however. Check with your local or long distance carrier
for applicable laws and regulations.
If possible, use WCR to shut down toll routes during out-of-business hours by
using Time-of-Day routing.
Digit Conversion
Digit conversion allows you to identify numbers, area codes, or countries you do
not want called. Whenever the numbers entered correspond to the numbers on
the conversion list, the numbers are given a different value, such as 0, and then
forwarded to the new destination, such as the attendant console.
 For DEFINITY G1 and G3i, the conversion can be to “blank” (intercept
tone), or to a Route Number Index (RNX) private network number, where
Private Network Access (PNA) software is required to route the call
through AAR.
 For DEFINITY G2 and System 85, the conversion is to an RNX private
network number, and AAR software is required.
 For DEFINITY G1, G2, G3i, and System 85, once the call is sent to AAR
software, the RNX can be translated as “local,” and the call can be directed
to an internal station or to the attendant console.
