Before you begin

Call back works by calling the number you've set up for Single Number Reach. So, you first need to add the number you want to use for call back as a Single Number Reach number. You can do this on the desktop app or the user portal.
1

From your mobile app, tap your profile picture, go to Settings, tap Calling, then tap Manage My Numbers and enable your call back number.

Tap Connect to device in the top left corner and then select that same number from the list.

3

Make your call from Webex App.

When your call back number starts to ring, answer the call.

Your phone then rings the person you're trying to reach.
