Overview

Automatic Number Identification (ANI) or Calling Line Identification (CLI) is a form of caller ID that sends a caller's phone number to the system before the call is answered. This allows you to join a meeting without having to enter a meeting number. When you call in to the audio portion of a meeting, the system verifies the number that you called in from against the number added to your Webex site preferences, and then directs you to the correct meeting.

To enable ANI/CLI Authentication, first enable it on your Webex site, then turn it on for each user. If you enable ANI/CLI authentication for users with host accounts, then they can:

  • Schedule a meeting with dial-in ANI/CLI teleconferencing authentication.

  • Specify a phone number to be authenticated when they call in to any ANI/CLI-enabled audio conference. However, they'll be authenticated only if they were invited by email during the scheduling process.

  • Specify an audio PIN to prevent a person from using a fake number to dial in to meetings.
