Daisy-Chaining (Pairing) Two Polycom Trio Systems (8500/8800)



Daisy-chaining two Polycom Trio Systems is a feature that has been added recently by Polycom since the Trio UC Software 5.8.0 :

"You can daisy-chain (pair) two Polycom Trio systems for enhanced audio performance in large or acoustically challenging rooms. When you daisy-chain Polycom Trio systems, the speakers and microphones act as a single speaker and microphone array for superior acoustic performance.You have the option to pair one Polycom Trio™ Visual+ system, Polycom Trio™ VisualPro system, or Polycom®RealPresence®Group Series system with your daisy-chained Polycom Trio systems".

This also works when using the Polycom Trio's Hub as a USB device (as illustrated above).

The step-by-step process  has been explained in a FAQ post on the Polycom's forum by Steffen Baier, Polycom Employee & Community Manager :

1) Set the network device role.

3) On the Hub Trio, select the device to pair to.

4) You may have to set maxDevices higher than 1.
