12.2.5 Using RADIUS Authentication for CLID
To use RADIUS for CLID authentication, create a user record in the users file where the user
name (the first field) is the telephone number, and the password (the second field) is always
Zyxel-CLID (case-sensitive). The regular user name is put in a User-Name field. The following
is an example of a CLID user record:
5551212 Password = “Zyxel-CLID”
User-Name = ”joeuser”
Zyxel-Callback-Option = Mandatory
Zyxel-Callback-Phone-Source = Preconfigured
Dialback-No = “5551212”
Note that if CLID is turned off in your Prestige, you need to have a separate user record for
joeuser so the regular user name/password mechanism still works.
