• The 8800 14.4(1) release notes state that the latest Unified CM firmware must be installed on all Unified CM servers in the cluster before the phone firmware release is used. in context
• 8800 firmware 14.4(1) ships as signed COP files named cmterm-88xx-sip.14-4-1-0001-36.k4.cop.sha512 and cmterm-8845_65-sip.14-4-1-0001-36.k4.cop.sha512 for the video models. in context
• The 8800 14.4(1) release notes require the latest device package on Unified CM and warn the firmware may not work correctly without the required package. in context
• Downgrading an 8800 phone from 14.3(1) or later to a release below 14.3(1) may lose ringtones on multi-line phones, which a factory reset resolves. in context
• To install a k3 or k4 COP file on a Unified CM release earlier than 10.0.1, the Readme for ciscocm.version3-keys.cop.sgn must be consulted to see whether that key COP is needed first. in context
• 8800 firmware 14.4(1) lists Unified CM 8.5(1) and later as the minimum supported call-control release. in context
• Firmware upgrades over the phone's WLAN interface can take longer than wired upgrades, possibly more than an hour. in context
