Using 1080p video for SIP/H.323 devices

Note: At this time, due to the increased platform usage, to ensure meeting stability, this feature is currently unavailable.

1080p video is available for H.323 and SIP devices in-meeting, for Business, Enterprise, and Education accounts. To use 1080p video, the bandwidth must be a minimum of 3mbps. 

Once Zoom Support has enabled 1080p for Room Connector devices on the account, an admin or owner will need to enable 1080p in account settings if it has not been enabled for the Desktop Client already. 

Note: Zoom recommends provisioning the device using the Enhanced API Connector when using this feature.
