Zoom Room Optimization, SCEP Function, HELD Enhancements, and Fixes

Improvements

Trio Optimized for Zoom Rooms
Trio 8500 and Trio 8800 systems 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.
This software release runs Zoom Rooms Controller software5.8.0 (898) as embedded software. For more information on this Zoom release, see the Zoom Help Center.
For the latest setup instructions, see the IntegratingPoly Trio Systems with Zoom Rooms Solution Guide at Poly Solutions for Zoom Environments.

HTTP-Enabled Location Delivery Enhancements
This release provides enhancements to the handling of HTTP-Enabled Location Delivery (HELD) requests. These HELD enhancements help emergency dispatchers determine the phone's most up-to-date location during an emergency call. The enhancements in this release are enabled by default and require no further configuration.
HELD requests now include the phone's user-agent string. HELD requests also support the attribute to provide the exact date and time the phone must reconnect to refresh its location data.
The phone defaults to a 24-hour HELD refresh interval and ignores the 'expires' attribute if:
● It can't calculate an expiration interval due to an error.
● It doesn't have an SNTP connection.
● The calculated expiration interval is greater than 48 hours.
If any HELD refresh request fails to receive a response, the phone doesn't clear any locations from its
memory. Instead, it uses the last successful location received to ensure it always has location data and
retries the HELD refresh using the value set in the 'feature.E911.locationRetryTimer' parameter.

USB Optimized Base Profile Default eterSettings Update
This release contains updated default settings in the USB Optimized base profile for the following parameters:
dialplan.x.digitmap.timeOut
Set the time, in seconds, the phone waits before selecting the digit before placing a call when
the phone is off-hook.
USBOptimized Setting-4 (default)
0-100 seconds
Change causes the system to restart or reboot
dialplan.userDial.timeOut
Set the time, in seconds, the phone waits for digit before placing a call when the phone is on-hook.
USBOptimized Setting-0 (default)
0-99 seconds
SCEP Certificate Signing Request Updates
You can now configure the phone's Locality (L) and Organizational Unit (OU) fields for CSR generation from the phone's system web interface in Settings > SCEP > Distinguished Name.
If you leave the SCEP.csr.commonName parameter with the default null setting, the phone now automatically uses its MAC address for the common name (CN) when it generates a CSR.

Bug fixes

Interoperability - Cannot present VbSS content in this conference was observed onTrio8800 running 7.2, when receiving content in a SFB meeting

User Interface - RealConnectdial string from Teams meeting Invite was not being parse

User Interface -The Hold button is not available from the Trio C60UI during a call When using a Trio C60phone in Skype base profile as a USB audio device attached to a PC.

Open issues

Content - If you share content using Video-based Screen Share (VbSS) and switch directly to Remote Desktop Protocol (RDP), the content sharing fails (Workaround: Restart the failed RDP content sharing to restore it. To prevent the content sharing from failing, manually stop the VbSS before starting RDP content sharing.).

Device Management -The system web interface doesn't show the correct time if you change the device time zone(Workaround: Log out and log in to the system web interface two times).

Directories - Pause characters programmed into saved contact information don't display in Recent Calls, preventing users from calling the contacts back from the Recent Calls list (Workaround: Manually dial the contact number, including the pause characters).

Interoperability - Mute controls must be managed from the Trio when running Zoom RoomConnector and ed over USB to MAC OS systems. If Trio is muted before joining a meeting, the ZRC application will not update its icon to show as muted even though the Trio will actually be muted, and all mute LEDs show red (Workaround: Use the Trio's physical mute button to unmute the Trio and resume mute state Sync.).

Logs - Occasionally, the phone logs scheduled informational messages at the higher than intended log levels. For example, default or minor Error messages log at event and debug levels. This error may interfere with the boot logs.

Network - While using Wi-Fi, the phone uses an IP address obtained from the DHCP server, even if a preferred static IPaddress was already configured (Workaround: Configure a static IP address using an Ethernet connection).

Network -When Wi-Fi is enabled and a static IP address is configured, the device fails to connect to the WebUI (Workaround: Configure a static IP address using an Ethernet connection.).

Network -Phone fails to obtain specific country IP addresses over wi-fi, where the country code setting leads to a selection of a 2.4Ghz Wi-Fi band (Workaround: a specific country where 5GHz is a default band. If the phone is on 2.4GHz Wi-Fi band reboot the phone after the upgrade to re-connect).

User Interface -When Trio is in Microsoft USB Optimized base profile, the menu permitting change of Trio's role between HUB or Device mode has obscured text informing you that Trio will reboot on applying this change.

User Interface -When enabling Wi-Fi, the phone reboots. When joining a Wi-Fi network for the first time, the phone's display gets stuck on the waiting screen with the messageObtaining IP address(Workaround: The connection is successful. the Back button from the stuck screen and begin using the phone).

User Interface -The Wi-Fi connection status always reports as not connected to the cloud server even when Wi-Fi is connected (Workaround: Hang up and redial until the tone
plays).

User Interface -The system web interface doesn't display the correct time if you change the device time zone (Workaround: Logout and login to the system web interface two times).
