To resolve the "outbound calling limit reached" error, ensure your Twilio number is properly imported into Vapi:
1. Go to the
Phone Numbers section in your Vapi dashboard and click
Import.
2. Enter your Twilio phone number, Account SID, and Auth Token, then click
Import from Twilio.
This step is required even if your number is from Twilio—numbers must be imported via the Vapi dashboard to be eligible for outbound campaigns.
For more details, see the [Vapi Outbound Campaigns Quickstart](
