Zoom Device Management(ZDM) is a device management tool, that allows you to manage your Zoom Rooms, devices and Zoom Clients without having to physically engage with each device.

Proxy server
We support https/SSL proxy server via port 443 for Zoom traffic.

Zoom automatically detects your proxy settings. In some instances, you may be prompted to enter the proxy username/password.
