Thanks for sharing the error details. To help troubleshoot, can you confirm if your new Twilio number has been fully verified and registered in the Twilio Trust Hub (including STIR/SHAKEN and CNAM, if required) and is associated with the correct SIP trunk in your Vapi dashboard?
This will help determine if the issue is due to verification or configuration steps, as outbound call restrictions often relate to these settings ([see documentation](https://docs.vapi.ai/phone-numbers/import-twilio), [Twilio SIP integration](https://docs.vapi.ai/advanced/sip/twilio)).

I CAN HELP @nishlocaldev
Hey! That error has nothing to do with your balance, Twilio blocks certain number types by default until you manually unlock geographic permissions in the console. Fixed this exact issue for two clients last week, clean 30 min fix.
Quick questions:
VAPI, Bland AI or straight Twilio?
Number you're calling: mobile, landline or toll-free?
Reply and I'll point you straight to it 🙌
