A conversation could not be created because your Twilio account is not authorized to use the provided Twilio proxy address.
- The outgoing conversation callback returned a Twilio proxy number that was created under a different Twilio account.
- Make sure that the
proxy_addressvalue that is returned from the Outgoing Conversation callback belongs to the Twilio account under which the conversation is being created.
- Check out the docs on how to configure your Twilio credentials in the integration service.
