A New Name – Poly Voice Software (PVOS)

Poly CCX business media phones, Poly Trio C60 and Poly Trio 8300 conference phones, and the new Poly Edge E Series desk phones join under a new software name to deliver a unified experience. The previous Unified Communications (UC) Software name began when video became part of the voice desktop experience. Poly has a growing portfolio of products offering a wide range of customized partner experiences spanning several operating systems, and Poly Voice Software (PVOS) brings together the best new features and communication enhancements from Poly in joint software releases.
Starting with version 8.0.0, Poly Voice Software (PVOS) is the new name for Poly UC Software. PVOS is now used in all technical documentation for Poly CCX, Edge E, and Trio series phones in this and all future releases.

Poly Fast Pair

Poly Fast Pair enables Edge E Series desk phones to recognize that a nearby headset has entered pairing mode. For supported Poly headsets, the phone presents an image of the detected headset and asks if you wish to connect. This feature bypasses the need to open the settings menu and manually navigate to the Bluetooth settings to pair manually.

Poly Fast Pair leverages Bluetooth Low Energy (BLE) to allow Bluetooth enabled Edge E series phones to recognize when a nearby compatible headset has entered pairing mode

Currently supported headsets:

● Voyager Focus 2 (v787_4266 or later)


● Voyager 4320 (v647.2725 or later)


Applies to products:
● Edge E Series


ICE, STUN, and TURN Support

The Interactive Connectivity Establishment (ICE), Session Traversal Utilities for NAT (STUN), and Traversal Using Relays around NAT (TURN) firewall traversal protocols are now available for SIP signaling and in-call media.


As a general example of configuring ICE, STUN and TURN the following configuration may be applied

tcpIpApp.ice.stun.server="Address of your STUN server"
tcpIpApp.ice.turn.server="Address of your TURN server"
tcpIpApp.ice.username="ICE username"
tcpIpApp.ice.password="ICE Password"

Additional parameters used for fine tuning ICE are:


The Parameter Reference Guides will offer some additional description of each of these parameters

Applies to products:

● CCX Series
● Edge E Series
● Trio 8300
● Trio C60

Accessibility Enhancements for Vision Disabilities

Edge E Series offers color correction modes to enable people who are color blind or have other vision disabilities to adjust the phone’s local interface.



Applies to products:

Zoom Rooms Controller

Poly Trio C60 phones optimized for Zoom Rooms act as a controller via the system’s touch user interface and provide audio for Zoom Room meetings through the built-in speakers and microphones. 

This software release includes the Zoom Rooms Controller version 5.11.0 (1386) as embedded software. For more information on this Zoom release, see the Zoom Help Center.


For the latest setup instructions, see the Integrating Poly Trio Systems with Zoom Rooms Solution Guide at Poly Solutions for Zoom Environments.

Microsoft Teams

The Microsoft Teams application is included in each PVOS release for use on CCX 400, CCX 500, CCX 505, CCX 600, and Trio C60 phones. The Teams version included may be updated independently of the PVOS version using the Teams Admin Center. For more information on this Teams version, see What’s new in Microsoft Teams.


Important:     PVOS includes the Microsoft Teams base profile in every release; however, Microsoft support of a release depends on the PVOS version delivered by Microsoft through the Teams Admin Center.
