ICE, STUN, and TURN Support Along With Fixes And Improved Network Subnet

Improvements

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 set has entered pairing mode. For supported Poly sets, the phone presents an image of the detected set 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.

• User Interface - Certain warning prompts display in English even if you change the phone's language to another language.
