Hey everyone, I am having an issue when I try to use the twilio to do the cold calling using an api and then error is coming like this: Couldn't Create Twilio Call. Twilio Error: Authenticate Can anyone point me in the right direction as if this is from twilio or vapi, as it was working this morning. I have created the phoneNumberId and then also check the status of the phoneNumber using the postman,

Hi there! 👋 Sorry to hear you're running into authentication issues with your Twilio integration. I'm unable to determine exactly what changed in your specific setup since this morning when it was working. However, I can definitely help you troubleshoot this "Twilio Authenticate" error and determine whether it's coming from Twilio or Vapi. A "Twilio Authenticate" error typically occurs when authentication fails between your application and Twilio. Here are the most common causes and troubleshooting steps: ## Check Your Twilio Credentials The most common cause is incorrect Twilio credentials. Make sure your Twilio Account SID and Auth Token are correctly configured in your Vapi setup. According to [information from Discord](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1333867863462903868), these values are crucial for authenticating with Twilio. ## Verify Account Status and Permissions Log into your Twilio dashboard and check: - Account standing (any notifications or alerts) - Positive account balance - Outbound calling is enabled - Geographic permissions for the countries you're calling According to [troubleshooting information](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336432457943351358), these are important checks when authentication errors occur. ## Check Phone Number Configuration Since you mentioned creating a

phoneNumberId

, verify that: - The phone number is active in your Twilio dashboard - It has voice capability enabled - There are no restrictions on the number - If using a free account, the destination number is verified ## Check Webhook Configuration Ensure that the webhook URL configured in Twilio for incoming calls is correctly pointing to the Vapi endpoint and not to a number, as mentioned in [this source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343208312249913397). ## Is it Twilio or Vapi?

The Authenticate error usually pops up when there are issues with your Twilio credentials (like the Account SID or Auth Token), if your account has been suspended, or if there are misconfigurations in your setup, make sure to double check your credentials, confirm your account status, and take a look at any recent changes also keep in mind that there could be service outages with Twilio, you can reach out to their support team

Thanks, I will check the credentials and be back to you
