Hello Mohammed,

DLU's are not version specific,  you can use Top Level part number LIC-CM-DL to purchase additional DLU's.

Best Regards,


Thanks Wilsy

  1. CP-7975G  --> QTY70
  2. CP-7965G --> QTY100
  3. CP-7942G--> QTY 150

  5. CP-9951-C-K9 --> QTY50

please advise with license or DLU part number can buy to add the above number of IP phones on CM 7.1.


Hi Sally,

You can use the same top level part number to order the DLU's needed "LIC-CM-DL".  The expansion module CP-7916 does not require a license.

If you have CM 7.1.5 you do not need to order DLU's but you will need the Enhanced license instead. You need to use top level part number L-CUCM-USR-LIC-ADD and select Enhanced license. The licensing scheme will be per device (70 CP-7975G = 70 Enhanced license).
