4.7 Configuring Incoming Calls from AT&T IP Flex Reach to BCM50
ConfigurationÆ TelephonyÆ Sets Æ All DNs:
We will now configure the “called number translation” (incoming) for the DN
number. In our example, go to the “Line Assignment” tab located at the
bottom of the “Line Access” page. Enter 2000 in the “Priv. Received #” field;
then enter the last four digits of the DID (Public number) in the “Pub. Received
#” (Note: 10 digit entries are now supported with Release 2.0). Incoming DID
calls will be routed to telephones, based on the trailing portion of the digits
received by the network. For example, Incoming calls from the AT&T IP Flexible
Reach network will deliver a ten digit DID number, e.g. 7323683478. The BCM50
will route the call using the last four digits, e.g. 3478. Additionally, this
configuration will allow incoming 4-digit dialing plan calls from the IP Flexible
Reach network, e.g. 3478.
