Hey all,
Relatively new to IP phones here. I setting several Cisco 8865's for our small office for use with Zoom Phone. I purchased a few refurbished models, all of which have 2015 firmware (the old blue interface). When following Zoom's provisioning guide, it instructed me to provision the phone via the local IP web interface.
The interface did not match any of the documentation, and there was no admin settings section. I attempted to update the firmware to the current version via tftp on tftpd32 thinking that would solve the issue. The firmware seemed to update successfully, but anytime the phone is disconnected from the network or TFTP is disabled, it reverts back to the 2015 firmware. Does anyone know why this may be?
Or perhaps this is irrelevant and I am taking the incorrect approach entirely. I have also read in the documentation that provisioning the phone will automatically update the firmware once completed, but I can't seem to get that far with the old web interface. Any thoughts?
Thank you very much!

In all likelihood, the FW version that they require is MPP/3PCC, if you're not running that version, you are running FW meant to be used with a Cisco call control where all the configuration is delivered by CUCM/CME.
You would need to change the FW to 3PCC/MPP at a cost, see upgrade.cisco.com
If they're running such an old FW, you'll also have to check if they even meet the version requirements to run 3PCC/MPP

If the phone is running such an old firmware, then there is a chance that the phone can be converted to 3PCC/MPP firmware for free.
