Getting this error- Couldn't Transfer Twilio Call. Error: Authenticate

Thanks for the response @Sarthak ( Vapi ) , do we need to check the auto token for each phone numbers added via twilio or is there any twilio integration page on vapi that we can check?

Yes you have to check for all phone numbers, usually one account have one auth token, and multiple phone number, so if updated, you have to update for every phone number.

Thanks! Updating the tokens worked. We can close this

Thanks.
