Synopsis

Configures
Verification of the called party
Default
None
Description
This command configures the interface to verify that the telephone
number being called (which is reported by the ISDN switch as part of
call setup) matches the telephone number of the router. By default,
calls are processed without verification. If this command is
configured, the router verifies the incoming
called-party-number before allowing the
connection. Using this command can reduce the potential for confusion
when several ISDN devices share the same ISDN local loop. Use
isdn
answer2 to verify a second
called-party number.
To list a called-party-number or a
sub-address, use any number of digits up
to 50; an x specifies a wildcard. You must specify
either the called-party-number or the
sub-address, but you are not required to
specify both. If you specify only one, the other is taken as a
wildcard.
