Hello guys,
In our office we purchashed new IP Phones just for a hardware renewal (from time to time).
The thing is that i got an issue when registering these 7821 model. The template wasn't present, so i guess that a new pack device should be installed in my CUCM.
Exactly, the CUCM version we have is the 8.6.2.21900-5
The latest device pack i obtained is cmterm-devicepack8.6.2.26169-1.cop.sgn
This device pack does not have the latest firmware of 78XX phone, so after installing the device pack I should upload the latest firmware cmterm-78xx.11-7-1-17.k3.cop.sgn of the 78XX phones on the call manager as well .
It will work fine with my current firmware version 8.6.2?
I'm kinda scared if i need to proceed with a full firmware upgrade to the Call Manager...
Thank you for clarify my doubts.
