Only use software version 6.1.9 when pairing Polycom Trio VisualPro or RealPresence Group Series 310 and 500 systems with Polycom Trio 8500 and 8800 systems version 5.7.1AB or later. Your RealPresence Group Series system must also be hardware version 20 or later.
Polycom UC Software 5.4.4AA should be used only with the Polycom Trio 8800 system for audio-only calling. After discovering issues with UC Software 5.4.4AA, Polycom has made the decision to withdraw support of UC Software 5.4.4AA for use with the Polycom Trio Visual+ system. Polycom recommends that you do not deploy UC Software 5.4.4AA with the Polycom Trio Visual+ system and use UC Software 5.4.4AB and newer instead. If you have any questions, please contact your Polycom support representative.
As of January 2017, Polycom began shipping the Polycom Trio 8800 with a new MAC ID/Serial Number range. The Polycom Trio Visual+ accessory is expected to start shipping with the same new MAC ID range in Q2’17. Prior to this change, all MAC/Serial Numbers began with 00:04:F2:xx:xx:xx. The new MAC ID/Serial Number range starts with 64:16:7f:xx:xx:xx.
