Enable CLI Authentication for Cisco Webex Meetings, Cisco Webex Events, and Cisco Webex Training in Webex Site Administration

If you use CLI authentication in Webex Meetings, Webex Events, and Webex Training sessions, you can provide your users with a greater level of security.


An Automatic Number Identification (ANI) or a Calling Line Identification (CLI) system is one form of caller identification that transmits a caller’s number before a call is answered. The number is sent to the system prior to the call being answered. The meeting number does not have to be entered into the joining form in order to join the meeting. You will be able to connect to the audio portion of a meeting by contacting the WebEx site preference website from the number you called in from, and the system will direct you to the correct meeting once the system has verified that number with the number you called in from.

ANI/CLI authentication can only be enabled once it is enabled on the Webex site, and once it is enabled for all users, it should work. It is possible for users with host accounts to use ANI/CLI authentication if you enable this option for them.

  • The ANI/CLI authentication service can be used to set up a meeting with dial-in participants.

  • In order to be authenticated, ANI/CLI-enabled audio conferences are required to specify a phone number that participants can call. It is, however, only those who have been invited via email as part of the scheduling process who will be authenticated.

  • A way to prevent the use of a fake number when dialing in to meetings is to specify an audio PIN which can be used.
