Note: It is not necessary to disable a security option, even if you are not using the option. The
security required for the authentication of each device will depend on the information
you have entered for that device. If, for some reason, you wish to disable an option,
select the Id of the option and press <RET>.

Validates the Calling Line information received when an ISDN connection is made. The system will
compare the incoming Calling Line Id with the value configured (if any) in the Device List. If the
numbers are identical the connection will be established. Otherwise, the system will reject the
incoming call.
When the Calling Line Id security is enabled, entering a Calling Line Id for each remote device is
optional. When two remote devices share the same line (a single point-multipoint ISDN line), they
can also configure the same Calling Line Ids if they both also have some other type of
authentication configured (for example, PAP, CHAP, or Bridge MAC Address Authentication).
The following table illustrates the dependencies between other authentication methods and the
Calling Line Id authentication:
