= H.323/SIP Room Connector = The H.323/SIP Room Connector is a gateway for H.323 and SIP devices like legacy Cisco and Polycom conference rooms systems. A H.323 or SIP device can make a video call to a Room Connector to join a Zoom cloud meeting. A Room Connector can also call out to a H.323 or SIP device to join a Zoom cloud meeting.  There are two options for the H.323/SIP Room Connector: * Cloud Room Connector (CRC) - Hosted by Zoom * Virtual Room Connector (VRC) - On-premise Both CRC and VRC are available to you when you purchase the H.323/SIP Room Connector add-on. When purchase a Room Connector you can subscribe to ports where each port subscription allows one device at a time to connect across all meetings in your account. If you have 5 ports subscribed only 5 conference room devices can connect to the Zoom cloud at the same time. To get an idea about what is and where is the Zoom room connector in Zoom architecture refer to the below diagram.
