Deploying the Virtual Room Connector

Last Updated:

Virtual Room Connector (VRC) is an on-premise gateway for H.323 and SIP devices. An H.323 or SIP device can make a video call to a VRC to join a Zoom Meeting.

VRC is offered as a VM installation on a private cloud. Having the VRC in your internal network allows internal SIP/H.323 device to join a Zoom meeting.  While having the VRC in your external network allows external SIP/H.323 device to join a Zoom Meeting (however 1-1 NAT or Port Forwarding can be set up on your network to allow the server to stay behind your firewall but accessible externally).

The Virtual Room Connector is packaged as an OVF and can be deployed onto any virtualization platform that supports OVF including:

System specifications for the VM can be found here.
