Hi All,


Need help regarding a customer licensing requirement. Customer UC background as below:


  • CUCM 6.1
  • Unity Express 3.1
  • Presence 6.0
  • 7900 Series IP phones


They are currently licensed under DLU. They are purchasing new 7900 Series IP phones. Seeing that DLUs are no longer orderable, the new IP phones will have to be licensed based on users (UCL or CUWL).


If, for example, we decide to go with UCL (CUCM Enhanced and Presence only, as Unity Express is not supported by UCL) + UCSS for the new phones, kindly advise:


  • the impact this will have on the existing DLUs? Will they still work?
  • how will Unity Express be licensed for the new phones?
