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.
  • 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.
