We need to transfer the Twilio phone numbers currently used in Vapi to a new sub-account in Twilio for management purposes. This transfer will change the Account SID and Auth Token values. As a result, all phone numbers configured in Vapi need to be updated with the new credentials. Is there a way to update all Account SID and Auth Token values in Vapi at once, in bulk, instead of updating them one by one?

Thanks for your question! Based on the documentation I found, Vapi allows updating Twilio credentials for each phone number individually via the API, but I did not see a built-in bulk update feature. To help you further, could you clarify if you are looking for a solution via the Vapi dashboard, or are you open to using the API (possibly with a script) to automate updating all numbers?

Hi Armin, To import a Twilio phone number into Vapi, you can follow these steps: 1. **Buy a Phone Number in Twilio**: If you don't have one yet, purchase a number in your Twilio console. 2. **Get Twilio Credentials**: Retrieve your Account SID and Auth Token from the “API keys & tokens” section of your Twilio console. 3. **Import Your Number in Vapi**: Navigate to the "Phone Numbers" section in the Vapi dashboard, click on “Import,” enter your phone number, and provide your Twilio credentials. Finally, click “Import.” For more detailed guidance, refer to the [Import number from Twilio guide](https://docs.vapi.ai/phone-numbers/import-twilio). If you have a significant number of phone numbers to import, note that there's no bulk import feature through the dashboard or API at the moment, so each number needs to be imported individually.
