Version: 4.4.6670.20201130

New and enhanced features

  • Notification of encryption status
    The encryption status of devices joining via the Virtual Room Connector will now be reflected in the upcoming Zoom client 5.4.6 release.
    Note: If the Virtual Room Connector is not updated, SIP/H.323 devices connecting via VRC will not be reported as encrypted to meeting participants with the Zoom 5.4.6 client. After January 10th, 2021 devices connecting via the VRC will be unable to send audio and video to participants on Zoom client 5.4.6. Due to this, we recommend updating the VRC appliance as soon as possible to minimize the potential impact.
