I want to order a call manager capable of supporting 500 users.Can you tell me if the selection i made is right?
If not make a suggestion
The minimum you can order is 10 at a time. So for 1 7911 phone (which uses 3 device lisence units), you would order LIC-CM-DL-10=.
I have attached an excel spreadsheet that you can use to calculate exactly how many DLU's you require.
The 7911s weighting is 3 and the 7961s are 4, so you would only initially need 46 DLU's. However if you were extending to say 400 7911's and 100 7961s, you would require 1600 DLU's in total.
Hope this helps,
