New subnet information for use and several new enhancements

Improvements

Subnet Information for use in E911 Location Identification

• The phone’ s current subnet length has been added to the LLDP sourced switch port and chassis information provided in SIP REGISTER messages. This information is shared in the X-Switch-Info header and is used to improve location identification in E911 calls.

Microsoft Support

• Trio 8800 Collaboration Kits, Trio 8500 Collaboration Kits, the Trio VisualPro accessory, and the Trio Visual+ accessory are not supported or qualified by Microsoft. As determined by Microsoft and Poly, the only supported way to connect Trio 8800 Collaboration Kits, Trio 8500 Collaboration Kits, Trio Visual+ accessories, or Trio VisualPro systems with Microsoft Teams or Skype for Business is through Poly RealConnect

Microsoft Environment Interoperability

• The following table lists Microsoft environments supported by Trio 8500 and Trio 8800 systems and the Trio 8500 or Trio 8800 Collaboration Kits that include the Poly Trio Visual+ system and a supported camera. This also applies to Trio 8500 and Trio 8800 systems when paired with a Trio VisualPro accessory and a supported camera

Zoom Rooms Controller

• Trio 8500 and 8800 systems, when optimized for Zoom Rooms, act as a controller for Zoom Rooms via the system’ s touch user interface and provide audio for Zoom Room meetings through the built-in speakers and microphones
