when to use CCM or CCME licenses for IP Phones

[reycapoy]

Hello,

   I would like to ask as to when are we going to use CCM or CCME to pair it with a particular IP Phone.  For example the for the 7900 Series.

What the client says that the existing VOIP Server is Cisco CallManager V5.0(2).  Shall I use CCM or CCME?

Thanks,

Hi,

CUCM is full blown call manager application running on a server. Whereas cme is call manager express running on a router.

As you mentioned the client is running cm 5.1, you'll use cm licenses.

Hi Saurabh,

     When we say server, does it mean a Windows Server? When you say "you'll use cm licenses" does this mean to give

SW-CCME-UL-7942  Communications Manager Express License For One 7942G Phone taking into consideration that a 7942G is being asked.

What things should I ask if in case for a example, the client did not inform at first hand, what type of call manager they are using, and they just ask for a 6921 IP phone..  What is the word to look into or the catch to exactly know what license sto give.

     For example:  client is asking for a 7942G and says that they are using  CUCM / Cisco Unified Communication Manager version 8.6. Does this mean the corresponding license to give would be the  SW-CCM-UL-7942        CUCM 3.x or 4.x RTU lic. for single IP Phone 7942.  Another thing that confuses me is the CUWL or UCL.

   Thanks,

As of CUCM 5.0 it runs on Linux appliance not Windows as it did prior to that version.  Keep in mind that current version is 9.0, so 5.0 is pretty dated. Licensing on version 5.0 was using Device License Unit (DLU) model where each phone model requires X number of DLUs (4 being the most common). If customer needs to purchase additional DLU licenses the part number if still orderable would be something like LIC-CM-DL-10= for 10 DLUs, LIC-CM-DL-100= for 100, etc.

For version 8.6 you would quote either CUWL license or UCL as Cisco migrated from device based licenses to user type licenses. If you are a partner reselling CUCM you should read the CUWL ordering guide:

And to add to Chris....

For non-dlu cucm versions, you do not need a phn license which you mentioned in your post. What all you need is a user license..that could be either CUWL or UCL.

Hi Saurabh,

           Thank you for the additions.  By the way I would like to ask if what are dlu cucm versions and non-dlu cucm versions and how do we know it?  Does refers to the version of call manager?

Thanks,
