How Interactive Voice Response (IVR) works

Number sign

1. Advertise a local number

Your customers call a toll free or local virtual number to reach your business. They can also call back the same number you used to reach them via SMS.

2. Customers call your business

When they call, your customers are greeted with pre-recorded voice or text-to-speech prompts, including a menu of options they can select by pressing keys on their phone.

3. Customers help themselves

Customers can accomplish many routine tasks in the IVR without agent intervention and can easily transfer to an agent who will have the context of their call when answering.

4. Your application adapts

As conditions such as queue length change, the call flow adapts automatically to better service customer needs, based on your application logic.
