Configuration – Security > Calling Numbers
Note:
This feature is for use by experienced personnel for network testing and fault diagnosis. It
should not be 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 may be answered normally or alternatively rejected with an optional reject code.
This web page contains a table that accepts a series of telephone numbers, each of which
has an associated Answer or Reject parameter and in the case of numbers from which calls
are to be rejected, a user-defined reason code. For each number set to “Reject”, the router
will reject incoming calls from that number using the reason code specified. The reason code
is simply a numeric value that is chosen to suit the particular application. If any one of the
entries is set to “Answer” the router will only answer incoming calls from that number and
will reject calls from other numbers using a standard ISDN reject code.

Mode
The drop-down list in this column selects either “Answer” to answer calls or “Reject” to
reject calls.

The value in this text box is the reason code pertaining to the rejection of the call.
