Polycom Labs Experimental Features:

• Large Room Audio Coverage (Audio daisy-chaining over IP)

This release includes a Polycom Labs experimental feature that allows you to pair two Polycom Trio systems (with or without a paired Polycom Trio Visual+, VisualPro, or Group Series system) via IP for enhanced audio performance in large or acoustically challenging rooms. When the two Polycom Trio systems are paired, the speakers and microphones act as a single speaker and microphone array for superior acoustic performance.

Implement Audio Daisy-Chaining over IP

To improve audio in large or acoustically challenging rooms, you can pair two Polycom Trio systems to achieve a single speaker and microphone array for superior acoustic performance.

Before you begin, you must ensure that:

1. Both Polycom Trio systems are connected to the same network subnet.
2. The network supports multicast and multicast is enabled.
3. Both Polycom Trio systems are running UC Software 5.7.2AA or later.
4. The parameter mr.pair.maxDevices="2" or higher

The following refers to Trio A and Trio B to help distinguish device behavior as you complete steps.

Procedure

1. On Trio A, go to Settings > Advanced > Networked Devices, and set Networked Device Role to HUB.
2. On Trio B, go to Settings > Advanced > Networked Devices, and set Networked Device Role to DEVICE.
   Trio B may reboot. If Trio B does not reboot, reboot manually. Note that the Trio B set to DEVICE must reboot for the setting to take effect.
3. After the Trio B reboots, follow the onscreen instructions that display on the Trio A and Trio B to complete the pairing.

In addition we fixed various filed issues as noted in the release notes.
