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 events with is added to your WebEx preferences.
You call into the audio portion of the event.
The system verifies the number that you called in against the number added to your WebEx preferences.
You are directed to the correct event without entering an event number.
If you have a host account and your site is enabled for ANI/CLI, then you can
Schedule an event 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 are 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.
