# 48028: Outgoing conversation: Unauthorized use of the proxy address

Log Type: APPLICATION

Log Level: ERROR

## Description

A conversation could not be created because your Twilio account is not authorized to use the provided Twilio proxy address.

### Possible causes

* The outgoing conversation callback returned a Twilio proxy number that was created under a different Twilio account.

### Possible solutions

* Make sure that the `proxy_address` value that is returned from the Outgoing Conversation callback belongs to the Twilio account under which the conversation is being created.
  * Check out the [docs](/docs/frontline/nodejs-demo-quickstart#configure-the-twilio-frontline-integration-service) on how to configure your Twilio credentials in the integration service.
