When Avaya Vantage™ Connect is the active telephony application on Avaya Vantage™, you are automatically logged in to Avaya Vantage™ Connect when you log in to the Avaya Vantage™ device. You can log in to the device by using either SIP or Avaya Aura® Device Services credentials. If you use Avaya Aura® Device Services credentials, which are applicable only in the Avaya Aura® environment, you might also need to provide your SIP credentials.
