# 48030: Outgoing conversation: Proxy address is not WhatsApp-enabled sender

Log Type: APPLICATION

Log Level: ERROR

## Description

A WhatsApp conversation could not be created because the provided Twilio proxy number is not a WhatsApp-enabled sender.

### Possible causes

* The Outgoing Conversation callback returned a Twilio proxy number that was properly formatted, but not configured as a WhatsApp-enabled sender.

### Possible solutions

* Make sure that the `proxy_address` value that is returned from the Outgoing Conversation callback is a WhatsApp-enabled sender.

  * Check out the [docs](/docs/whatsapp/api#using-twilio-phone-numbers-with-whatsapp) for how to configure WhatsApp-enabled senders as a Twilio proxy number.
  * Manage your WhatsApp-enabled senders from the [console](https://twilio.com/console/sms/whatsapp/senders).
