:bullseye: What is your goal?

Need proper setting in Make to set numbers of calls using Vapi.com per session or per day.

:thinking: What is the problem & what have you tried?

I have 10 twilio numbers in Vapi and want to run 30,50 or 100 calls in rotation. I have the out going numbers indexed (not the problem). Problem is, If I set to 50 calls in Make then Vapi wants 50 numbers to dial. Why arn’t the calls rotataing to the next available open phone line in Vapi?

:clipboard: Error messages or input/output bundles

error from Vapi, "Concurrency limit (10) reached. Purchase more phone numbers.

You can try doing this workaround for your system. I hope this will help you solve your problem.

First scenario runs once to load all the target numbers into a simple list (Make.com Data store, Airtable, or Google Sheets), marking each entry as “waiting” or “pending”.

Second scenario (rate-limiter) runs on a schedule (for example, every 1-5 minutes), looks at that list, and picks at most 10 “waiting” or “pending” numbers each time. It starts calls for those 10 via Vapi and marks them as “in progress” or “done”.

This way, Make.com never launches more than 10 calls in a single burst, and Vapi can rotate through your 10 Twilio numbers without hitting the concurrency limit.
