Vapi is the Voice AI platform for developers.

Vapi AI

I've come across the outbound calling not working sometimes when dialing specific numbers.  Not sure if its a spam detection thing or not.

My other question is, is there the ability to make 5-10 concurrent calls?  Leveraging the API or make.com maybe?

Also, you can make 10 concurrent calls and you can use the API

My goal is to ultimately have an autodialer setup that is constantly pushing out 10 concurrent calls for about 2-4 hours.  Will I be hitting rate limits if I do that.
