Hi Harisivaji,


The Seat License is = to the number of users, so for your an Enterprise with 900 users you might order a 1,000 "Seat License". Licenses are generated for requested Cisco CallManager nodes (servers in a Cisco CallManager cluster - with seats) and the phones that are associated with those nodes (DLU's).

Hope this helps!

Rob

Hi Rob,

Consider this following scenario:

One call manager server with 75 IP phones but none of the user has user based phone-web access to change any settings in their phone.


Here we need to purchase one server with One Node license and 100 DLU is it enough ? without seat license can we use it.

Hi Rob, hope everything is fine at your end. Sorry to jump in like this, but thought would answer hari's question wrt 75 IP Phones.


Hari,


If you want to have 75 IP Phones with one MCS server you need to have the following [sample] -


DLUs - let's say 7941s, 75 Numbers you'll need 75*4= 300 DLUs.

MCS server -

MCS7816H3-K9-CMB2 Unified CM 6.1 7816-H3 Appliance, 0 Seats

Seat/Node License -

LIC-CM6.1-7816= License Unified CM 6.1 7816 Appliance, 500 seats


HTH


Rob, apologize once again.

Hi Harisivaji,


Just to add to what Rob has mentioned, typically seat licenses are associated to your UCM cluster and is dependant on the MCS server.


Following are the seat licenses available -


LIC-CM6.1-7816= License Unified CM 6.1 7816 Appliance, 500 seats

LIC-CM6.1-7825= License Unified CM 6.1 7825 Appliance, 1,000 seats

LIC-CM6.1-7835= License Unified CM 6.1 7835 Appliance, 2,500 seats

LIC-CM6.1-7845= License Unified CM 6.1 7845 Appliance, 5,000 seat

LIC-CM6.X-2500= License Unified CM Additional 2500 Users


If you observe 7816 mcs server can support up to 500 phones hence you have the license of 500 seats. Similarly 7845 can support up to 7500 users. You have two licenses for 7845. If you are planning to have not more than 5000 users on a 7845 cluster then you can go for "LIC-CM6.1-7845=" license, however if you plan to have more than 5000 phones then you need to additionally order "LIC-CM6.X-2500=" license. Please note that For all the MCS servers apart from 7845 the number of seat licenses are available for the max phones supported. For exmple for 7835 cluster which can support 2500 phones, you can't order a 1000 seat license even if you plan to have no more than 1000 phones registered to the cluster.


Coming to DLUs, it's the number of licenses required per Phone to register to the UCM.


For example a 7940G IP phone consumes 4 DLUs.


Hope this clarifies.

Sushil,

What does it means,

CUCM Hardware SKUs:

MCS7825H3-K9-CMB1-Unified CM 6.0 7825-H3 Appliance, 0 Seats


Is it like we need to buy additional CUCM license LIC-CM6.0-7825=License CM 6.0 7825 Appliance, 1,000 seats

Hi Hari,


The part number you are referring to is the partnumber for UCM 6.0 Appliance = MCS + UCM 6.0 Software. It does not includes any seates.


Hence you need to purchase "LIC-CM6.0-7825" license, even if you has as low as 10 IP Phones registered to this server [hypothetical scenario :)].


Please note that you need to incorporate DLUs in addition to this.
