Firmware Compatibility

[Leonardo Santana]

Hello,

I have an doubt we have an CUCM 8.6 with 7911 and 7941 using the following firmwares:

7911 SCCP11.9-3-1-1S

7941SCCP41.9-2-1SR2S

We will put an CME 7.0.1 that was running before the CUCM 8.6 my question is, i see that CME supports this firmwares versions:

7911 SCCP11.8-3-3S.loads*

7941 SCCP41.8-3-3S.loads

Do i need to downgrade my IP Phones to version 8.3.3 if i keep versions 9-3 and 9-2 they will work?

Regards

Hi Leonardo,

We don't run CME except in the lab so I'm not an expert here

We do know that device firmware versions are not dependant or

related to the specific CME/IOS that you are running so you should be good to go.

You could always try to upgrade the CME with the matching firmware just in case

you add new phones and want them to have the same loads.

Cheers!
