After doing a firmware upgrade for a 7942 from SCCP42.9-2-1S to SCCP42.9-2-3S.
Im getting a Mismatched Load:
I already reset the tftp and the phones..
I need to know why CUCM reports a firmware mismatch for the updated phones?
We upgraded our CUCM from 7.1.3 to 8.5 SU3 and have a lot of these on 7961's, 7962, 6921's.
In CUCM go to Device, phones and locate a phone with a mismatch. Then click on that phone which will bring you to the phone config page, find "Phone Load Name" and put in the phone load you want, "Apply Config", "Reset" and give it 10 minute to upgrade, after that remove the phone load, apply, reset and that cleared it up for us.
These are 7961's but the same issue.
Hope this helps,
