# 32009: The user you tried to dial is not registered with the corresponding SIP Domain

Log Level: WARNING

## Description

There was a failure attempting to Dial the specified SIP Endpoint. The User specified is not registered.

### Possible causes

You tried to Dial a SIP Endpoint that is not currently registered with the corresponding SIP Domain. Please check your TwiML or REST API.

### Possible solutions

* If you are using TwiML Please check that there isn't a typo in \<Dial>\<Sip>**username**@yoursipdomain.sip.us1.twilio.com\</Sip>\</Dial> and compare against your SIP Endpoint configuration. Make sure the **username** matches a username in the Credential List used to authenticate the SIP Endpoint with the SIP Domain.
* If you are using the REST API Please check the **To** field and verify there isn't a typo. Make sure the **username** matches a username in the Credential List used to authenticate the SIP Endpoint with the SIP Domain.

### Troubleshooting

* Prior to dialing, you can verify that your SIP Endpoint has successfully registered in the Console "Registered SIP Endpoints" tab found on the SIP Domains page.
