upgrade firmware for IP Phones

Hi Experts,

I have upgraded my CUCM "Minor" from 6.1.2 to 6.1.5, everything is working fine, I need to enforce all my phones to upgrade their firmware currently there are still running their old firmware ….what is the best way to do such upgrade for my IP Phones.

Note the available Phone model is "7975,7961, 7960&7940"

Regards,

Saeed

First check the upgrade compatibility between the existing version and the default load on 6.1(5) - i.e., ensure no interim upgrades are needed.  If not, the easiest way to upgrade firmware is to update the device defaults for each device type and reset the phones.  Monitor via RTMT before and after so you have an accurate count of phones pre and post upgrade.
