Upgrading Your Phone’s Firmware

From time to time, Polycom may provide updated firmware that will enhance the operation of your phone. You or your system administrator may elect to perform the task of upgrading your phone’s firmware.

A special cable will be needed to upgrade firmware on the handset. This cable, along with upgrade instructions, will be made available in a Firmware Upgrade Kit that may be purchased separately.
