Configuring security
Set calling numbers to answer or reject
Note
Only experienced personnel should use this feature for network testing and fault diagnosis. It is
not required for normal use. To use this feature, the ISDN circuit must support the Calling Line
Identification (CLI) facility. If CLI is supported, incoming calls from specified numbers can be answered
normally or rejected with an optional reject code.

1. Go to Configuration > Security > Calling Numbers. The Calling Numbers page has a table
that accepts a series of telephone numbers, each of which has an associated Answer or Reject
parameter, and, for numbers from which calls are to be rejected, a user-defined reason code.
For each number set to Reject, the router rejects incoming calls from that number using the
reason code specified. The reason code is a numeric value chosen to suit the particular
application. If any of the entries is set to Answer, the router only answers incoming calls from
that number and rejects calls from other numbers using a standard ISDN reject code.
Number
The telephone number to either answer or reject.
Mode
The drop-down list in this column selects either Answer to answer calls or Reject to reject
calls.
Reject Code
The reason code pertaining to the rejection of the call.
2. Click Add to add the calling number.
3. Click Apply.
