Configuring Calling Line-Identification Screening

You can filter incoming calls to the Nokia appliance by using the calling number in the received SETUP message. The network must support Calling Line Identification (CLID) to filter calls by using the calling number.

When an incoming call is received, the calling number in the received SETUP message is checked against the incoming numbers configured on each logical interface. The calling number is compared with each incoming call using the right-most-digits algorithm. A number matches if the shortest string between the received calling number and the incoming number is the same. For example, if the calling number received was 345 and the logical interface has an incoming number of 12345, then this is deemed a match.

The call is answered on the interface that is configured with the incoming number with the highest number of matching digits. If no matching incoming number is found, the call is rejected.

If no incoming numbers are configured on an interface, any incoming call is deemed a match.

Detailed information on how to add and delete incoming numbers to the logical interface follows.

To add an incoming number

1.Click Interfaces under Configuration > Interface Configuration in the tree view.

2.Click the physical interface link in the Physical column. Example: isdn-s2p1

3.Click the logical interface link in the Logical Interfaces table.

4.Click the Incoming Numbers link.
