Issue with Vapi Webhook Handling Large Call Volume

Hey team — quick question about Vapi's call handling:

If I trigger a webhook to have the Vapi assistant make 100 outbound calls, will it automatically process all of them, or does it need to be done in a drip sequence? I know Vapi supports up to 10 concurrent calls, but when I recently triggered 100 via webhook, only a handful were executed — many are still pending and haven’t been dialed yet.

Any idea why that’s happening or how to ensure all calls get processed?
