New Features:

Trio 8500 systems support Zoom Room Controller (ZRC) 5.3.0 (214), including the latest security updates. For details, visit the Zoom Help Center.

Enhancements:

Fixed Bugs:

Users were unable to join meetings using Alexa for Business commands.
The phone may reboot repeatedly if the WPAD feature is enabled and configured with <code>feature.wpad.proxy="PROXY :"</code>.
When the subject field of a meeting invitation contains four-digit numbers, Trio sometimes incorrectly treats them as dialable numbers.
The phone continues to answer calls with the microphone unmuted when using the SIP alert-info configuration to auto-answer calls muted.
A synchronization issue in the REST API during calls lasting approximately 45 minutes may drop the call on Trio phones paired with a Poly Trio VisualPro and Polycom Pano system.

Open Issues:

On Poly Trio phones, the ringback tone may not play for the first several outgoing Teams calls after a reboot.
A Trio paired to a Zoom Room PC may not provide audio for calls using the Zoom Room PC 3rd Party Join feature to join Microsoft Teams calls.
When using OTD for calendaring and scheduling a BlueJeans Network meeting, all-day events sometimes show an incorrect meeting time.
Poly Trio phones reboot when attempting to failback to primary if the primary is unavailable.
Telnet appears to break when an incorrect username or password is entered.
If a user joins a Skype for Business conference call and quickly hangs up, the green LEDs may remain illuminated.
The Trio system may receive broadcast packets from the default VLAN when configured to use VLAN.
The system web interface may not display the correct time if the device time zone is changed.
During a conference call, if Trio receives multiple incoming calls that are all declined, it may reboot unexpectedly.
The Wi-Fi connection status may incorrectly report as not connected to the cloud server when it is.
