Good morning, I would like to know if its possible to setup an automated queue that would prompt a caller who to enter their phone number for call-back if we are unable to get to their call in-time. The scenario: 1. Customer calls in 2. Call center is swamped 3. After a set number of rings, the customer is prompted to either leave a enter a number to call them back or leave a voicemail Any help would be appreciated. Thank you.
