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.
