# Send a directed message

> Learn how to send a direct message to a user in the sample application.

When you send a [directed message](../../developer-guide/messaging/directed-text-voice) (account\_send\_message in the Vivox SDK), you need to know the URI of the participant, which starts with "sip:" and ends with "@mt1s.vivox.com".

The following code displays an example of the user Alice sending a directed message to the user Bob:

```plaintext
[SDKSampleApp]: message -u sip:.xyzzy.bob.@mt1s.vivox.com -m "hey bob"
* Sending directed message 'hey bob' to user sip:.xyzzy.bob.@mt1s.vivox.com
* Issuing req_account_send_message with cookie=3
```

Bob sees the message as a user\_to\_user\_message event:

```plaintext
* evt_user_to_user_message: .xyzzy.bob. sip:.xyzzy.sa_c78d1595.@mt1s.vivox.com - hey bob
```
