Legacy Zoom Connector for Cisco Follow


Note: Starting January 18, 2021, new accounts provisioned with Cloud Room Connector licenses will automatically have access to the new enhanced API Room Connector for SIP/H.323 devices. If your account was provisioned a CRC license after January 18, use our enhanced room provisioning and management instructions. 

If you have an existing Cisco or Tandberg room system in place, you can integrate its native calendaring system using the Zoom One-Tap Cisco Connector. This lets you start a scheduled Zoom meeting directly from your existing hardware. You can also start an instant meeting if the room is configured with a Personal Meeting ID, or use the room to join Zoom meetings that are not on the calendar.


General requirements

  • A Zoom account with a Cloud Room Connector license  
  • A Cisco or Tandberg system that is powered on and has all components connected, including a cable to your network and a connection to a TV screen. The system must be running TC 5.0.2 or higher or CE software to support OBTP (One Button To Push). - Learn more about supported devices and firmware
  • Network access to Cloud Room Connector
  • Calendar setup with Google or Exchange/O365

API Connector  requirements

  • A Windows PC, Server, or Virtual Machine (for installing and running the Zoom API Connector software locally
    • 2 core processor
    • 8 GB of Ram
    • 20 GB of storage

Note: The above device requirements, support up to 200 endpoints

Associate the Zoom Connector with your network

  1. From your browser, sign into Zoom, and click Cisco/Polycom Rooms.
    Note that if you do not already have a Cloud Room Connector license, this page provides instructions on how to purchase it.
  2. Click the API Connectors tab, then click Add API Connector.
  3. Enter the network information in the popup dialog.
    By default, the range covers all possible networks that your system might be using. You can limit this to the actual network and subnet information used with your Cisco system.
    Note: If you need to use multiple connectors, make sure that the network values that you specify for each connector do not overlap.
  4. Click Save.

The new connector, with an automatically generated Connector ID, displays in the list of API Connectors. The Connector ID, which is copied to your clipboard when it is generated, will be used in the procedure to install the Zoom API Connector software.

Install the Zoom API Connector software

The Zoom API Connector installer opens a wizard, where you enter the Connector ID (created in the previous procedure) associated with the Zoom cloud. Note that the API Connector software runs on a Windows Server or Virtual Machine.

  1. Sign in to the Zoom web portal.
  2. Click Room ManagementCisco/Polycom Rooms.
  3. Click the API Connectors tab, then click the Install action for the connector.
    This downloads the installer for the Zoom API Connector ready for installation and copies the Connector ID to the local clipboard for your convenience.
  4. If the ZoomAPIConnector.msi file was downloaded using a different computer than the one your are installing on, move the file to the installation computer.
  5. Double-click ZoomAPIConnector.msi to open the wizard and begin the installation process.
  6. Use the wizard pages to accept the license agreement and specify an installation location, then click Next.
  7. Enter the Connector ID in the Customize this installation page of the wizard.
    This is the value that was automatically generated in the procedure to associate the Zoom Connector to the network.
  8. Click Next, then click Install to install the Zoom API Connector software.
  9. After the installation is complete, click Finish to exit the wizard.

The Zoom API Connector is now associated with the network that includes the Cisco room system. The Zoom API Connector application only needs to be installed one time, regardless of how many Cisco room systems you need to configure.

Note: You must keep the Zoom API Configuration software running on a Windows Server, a Virtual Machine, or for short term testing, a Windows workstation. However, we recommend that once testing is complete, moving the API connector to a permanently running/powered on Windows environment for production.
