You can change the number that is used to call into Cisco Webex Meetings and Cisco Webex Events.

What is ANI/CLI Authentication?

CLI (caller line identification), or ANI (automatic number identification), is a form of caller ID.

Here's how it works:

The phone number that you call into meetings with is added to your Cisco Webex site preferences.
You call into the audio portion of the meeting.
The system verifies the number that you called in against the number added to your Webex site preferences.
You are directed to the correct meeting without entering a meeting number.

If you have a host account and your site is enabled for ANI/CLI, then you can:

schedule a meeting with dial-in ANI/CLI teleconferencing authentication.
specify a phone number to be authenticated when you call in to any ANI/CLI enabled audio conference. However, you will be authenticated only if you were invited by email during the scheduling process.
specify an audio PIN to prevent "spoofers" from using your number to dial in.

2	Go to Host a Meeting > Schedule a Meeting. The Schedule a Meeting page appears.
