Guys, I just want to make sure that I´m doing the right thing here, I have a client that needs to upgrade their voip network this is what they have:
· OS Image: 2000.4.1
· OS Upgrade: 2000.4.4a
· System Version: 4.2(3)sr4b
· Administration Verion: 4.2(2)
· Instalation ID: CCM4.2(3)sr4b
AnAnd I´m getting the: MCS7816I4-K9-CMD1 with the CM8.
Nonow, my question is, the reason I´m doing this, it is because I´m adding more users on the network. So, I´m buying License for the new phone (PN: LIC-CUCM-USR), now what about the phones that is already there? What is the part number that I need to get to upgrade my eisting phones that the license is 4.x to 8..x?
SoSome one can help me on this?
