Hey Frank and guys following this. I was and actually am in the same spot. Searching for the best AI Voice Agent to sell for my clients. After discussing with each of them, retell, vapi, eleven labs, eleven labs is the one that can offer the best deal in my opinion, Vapi uses their infrastructure so using vapi will just increase latency and cost per minute. Eleven labs will be the cheapest, offers support, they are one of the best in the world, you got everything you need inside. If you land a big client or a few smaller ones, you can apply to the Enterprise package, which includes white labeling and 24/7 priority support so you are covered. The bigger the package the cheaper per minute. In my opinion, is better to go to the source. Test it out and see yourselves.
