Any update on this?
Thanks for your patience while we dug into this.
Looking at call
019ae38f-47d1-7336-867d-e5fb2b1244ef, we’re seeing the following internal error on our side:
🔴 09:33:30:127 Couldn't initiate outbound call transport and queue for call 019ae38f-47d1-7336-867d-e5fb2b1244ef. Error: Couldn't Create Twilio Call. Twilio Error: Authenticate
This means Vapi wasn’t able to authenticate with Twilio when trying to start the outbound leg. It’s not related to your assistant configuration, but to the telephony transport step.
A few things to check on your side while we continue investigating:
1. Twilio credentials in Vapi
- Re-save your Twilio Account SID and Auth Token in the provider/phone number settings (in case the token was rotated or invalidated).
2. Twilio account status
- Confirm in the Twilio console that the project is active, has sufficient balance/credit, and outbound calling is allowed for your region and numbers.
3. From number configuration
- Make sure the Twilio number you’re using for outbound is still valid, SMS/voice-enabled, and not restricted.
