4.7 Configuring Incoming Calls from AT&T IP Flex Reach to BCM

ConfigurationÆ Telephony Æ Sets Æ All DNs Æ

We will now configure the “called number translation” (incoming) for the DN

number. First locate the desired private DN number that you want to assign the

public DID number under the “Line Access” tab. In this case we have selected

“DN 3000”. At this point, select the “Line Assignment” tab under the

“Details” window. Enter 3000 in the “Private Received” number field; then

enter the last 4 digits of the DID (Public number) in the “Public Received”

number field. 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. 7323683476. The BCM will route the call using the last four digits, e.g. 3476.

Additionally, this configuration will allow incoming 4-digit dialing plan calls from

the IP Flexible Reach network, e.g. 3476.
