we are going to deploy Ip telepony solution in our company. We have 100 users and need 100 Ip phones and we also need voice mail for everyone.
I tried selecting devices via CISCO Dynamic configuration tools, but not sure our selection is correct or not. So I listed a few qestions:
1). Do I need license for my IP phone(I choose 10X7961 phones and 90X7911G phones)? If yes, I select: "LIC-CCM-7960+COM= CallMgr User License 7960/61 And IP Comm, Single License", is that right? What should I select for 7911G license?
2). Does CCM also need 100 license? Because I saw an item" LIC-CM-DL-100= CallManager Device License - 100 units", not sure whether this should be selected or not.
3). How about Unity license? we need 100 user all have voice mail, which part number I should select for this license?
4). What is "unity conection"? and what is the difference between "unity server" and this?
