Polycom firmware update required

Starting by the end of June 2016, Polycom introduced a new MAC address range for VVX, SoundPoint IP, and SoundStation phones, as well as SoundStructure Installed Audio products, due to exhaustion of the current 00:04:xx:xx:xx:xx MAC address range. Phones with a MAC address in the range 64:16:7f:xx:xx:xx require a firmware update, which is included in currently supported CIC patch releases, starting with CIC 2015 R2. Newer phones without the firmware upgrade may fail.
