Call-by-call routing
By default, incoming calls are routed based on the Called Party Number. You program the received number length to include however many digits your system requires. This many digits from the end of the called party number are then used as Received Digits to find a target line.
For example, the incoming calling party number is 800-555-1234. The received digit number length is 4. Therefore, 1234 is used to route the call.
Depending on the protocol and the service, alternate routing maps may be defined.
