Twilio Number — Still Hitting 10-Call Limit?

Hi Team,

I’m seeking clarification regarding Vapi’s concurrency limits. I recall reading that once a Twilio phone number is integrated with Vapi, the default concurrency limit (e.g., 10 simultaneous calls) no longer applies. However, I’m still observing this 10-call concurrency cap even after provisioning and using a Twilio number.

Could you please help me understand how the concurrency limits work in this context — specifically, under what conditions (if any) they’re lifted or increased when using Twilio numbers?
