I have imported a phone number from Twilio to my VAPI account. However, when I am trying to make an outbound call, it's giving me an error. Here are the details:

That “get transport” error usually points to a SIP/telephony transport issue between Twilio and VAPI, most times it’s tied to the imported number setup, SIP trunk config, or outbound voice permissions. I’ve worked on similar VAPI outbound call issues and can help you trace the exact cause quickly. Did you import the number through Twilio SIP trunking or directly via Twilio credentials/API? Also, have you confirmed the number has outbound voice enabled inside Twilio for US calls? @VJ

I have calling service enabled on my Twilio account. I have been using this account for a long time. I imported the number using the Twilio API creds.

Hi, I checked the failed call (

019e2d50-d222-799d-a9c0-6018d344ca3e

) and the issue is coming from Twilio. Twilio rejected the call with:

Account not allowed to call +13155333019

Most likely causes: • Twilio account is still on trial • US geo permissions are disabled • Destination number is restricted Please check: 1. Twilio Console → Voice → Settings → Geo Permissions → enable United States 2. If on a trial account, verify the destination number or upgrade the account Then retry the call.
