• Peripherals VOICE- 74614 CCX After connecting a Bluetooth headset and then making a call by deliberately using the handset or handsfree speaker, switching to the headset during the call results in no headset audio until the audio termination is switched from the headset and then back again. This issue only affects the first call made this way.

Open problems

• Application VOICE-74984 Trio When Trio operates as a Zoom Room Controller, searching for a reaction emoji during a meeting for the first time after a reboot may cause the app to pause for too long and trigger an Application Not Responding error on screen. Select Wait and the Zoom Room Connector application recovers.
• Call Management VOICE-21852 CCX If a user places a Teams call on hold using their Teams PC client, the connected CCX phone in USB phone mode can't mute the microphone using the mute button. Resume the call then mute the microphone with the mute button.
• Call Management VOICE-21852 CCX If a user places a Teams call on hold using their Teams PC client, the connected CCX phone in USB phone mode can't mute the microphone using the mute button. Resume the call then mute the microphone with the mute button.
• Interoperability VOICE-71713 CCX Microsoft Exchange calendar on CCX and Trio incorrectly displays a canceled meeting if that occurrence within a series is canceled. No workaround
• Interoperability VOICE-67871 Trio Mute controls must be managed from the Trio when running Zoom Room Connector and linked 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. Use the Trio's physical mute button to unmute the Trio and resume mute state Sync.
• Wi-Fi VOICE-71710 CCX CCX does not apply the Wi-Fi Country of Operation setting when it is changed from the Web interface or the Admin Menu and must be manually rebooted for it to take affect. Change the country of operation and then reboot.
