4.8 Configuring Incoming Calls from AT&T IP Flex Reach to a BCM450
DN
Configuration

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 (or however many digits specified in Figure 9) of
the DID (Public number) in the “Pub. Received #” column. 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 BCM450 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.
