So do you mean if I have 50 phones in the system, which means 50 user licenses?

if you mean creating users and associate them to the phones the answer is NO

the licensing model in which every phone needs a certain amount of DLUs to work was introduced in CUCM 5.x and will continue in further releases.

In the new versions there is also no license for just creating end users. If you want a special capbility like presence or some others then you do need to have the license for that.

in CCM 4.x and before there are no bindings between phones and licenses, or user/device and license.

you can have 100 users if you want because you want them to be in the directory and only 50 phones (this really doesn't make sense in the real life but it's just an example) and there is no licensing issue

My question is we using CCM version4.1 now and I have no idea how many users(phones) I can continue to add into the system before reach the license limit. If so, I need to purchase more user licneses.

Which tool can I use to view the licese limit?

Hi Jeff,

You don't need to worry about this in CCM Versions before CCM 5.x :) These licensing restrictions were not implemented until that version.

With CCM 4.x you bought the Phone with the License and are good to go!

Hope this helps!
