Install AI call agent to my website

Description

I want an AI call agent built to cold call customer who have filled out an online quote on my website and haven’t booked.
To answer any questions they have about the service, make sure they have every they requested when getting a quote. A few basic things / questions. The end goal is just making sure they are happy with the quote and if they need any further assistance with booking.
I have my front end capturing the numbers - we will need to have an automation so check if they have booked or not. My website is Wordpress but I have a front end developer who can help with anything we need to take from the front end.
