Hello all,
we are pleased to annouce the release of the Polycom Trio UC Software 5.7.2 Rev AA.
New Features:
- Polycom Trio System Support for Cisco WebEx
The Cisco WebEx application enables users to join scheduled meetings with one click. Note you cannot host a Cisco WebEx meeting on a Polycom Trio system.
For instructions, see the Polycom Unified Communications for Cisco WebEx – Deployment Guide on Polycom Support.
- Simple Certificate Enrollment Protocol Parameters
Use the Release Notes documented parameters to configure Simple Certificate Enrollment Protocol (SCEP).
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:
- Both Polycom Trio systems are connected to the same network subnet.
- The network supports multicast and multicast is enabled.
- Both Polycom Trio systems are running UC Software 5.7.2AA or later.
- 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
- On Trio A, go to Settings > Advanced > Networked Devices, and set Networked Device Role to HUB.


- 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.
- 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.
