Hello All,
Our customer has CUCM ver. 11.0.1.20000-2. I would like to register two different phones, but I should uprage these phones Firmware.
What is the recommended Firmware at these phones?
The phones type are 7940 SCCP and 8845 SIP.
Thank you,
Kind Regards
Tamas

Register them to CUCM and then upgrade at device level if that's what you want.
Recommendation is to always run whatever is the latest FW, review the README/RN to determine if you can upgrade directly from whatever FW they're running or not.

Compatibility is mentioned in the downloads page as well as the RNs for the FW.

As Java wrote the release note for the phone firmware should contain information about compatibility. Usually there is no problem in using newest version of firmware on the phones as it’s not directly related to the version of the CUCM. But you’ll need to do your due diligence and read up before you go about with this.

For the 7940 / 7960 there were some firmware versions that needed an intermediate upgrade. For that reason we've seen customers with these phones stuck in the past so to speak, for example if they did a CUCM major version upgrade and let the phone loads do their own thing.
The OP says these phones are SCCP, but the version number he quotes looks like SIP?

The 7940/7960 was designed to be SCCP phones, the SIP firmware likely has a few limitations, but might work for what you use. If you do find limited function I would recommend to convert these phones to SCCP.

It is, but, you may need to install a device pack to enable it, which will shift firmware versions for things (probably backwards at this point). You could then move the endpoint firmware up if it's compatible with your software.
UCM 11.0 is end of maintenance, support ending in a couple of months for current contract holders.
