Use Meet with 3rd-party video conferencing systems

As an administrator, you can set up Google Meet to let participants join your organization’s Meet video calls from third-party video conferencing systems.

To join Meet video calls, third-party systems must be standards-based (SIP/H.323), and they can be located inside or outside your organization. If a third-party system has calendar integration that supports SIP URI (uniform resource identifiers), participants may also join Meet calls with a single touch.

Supported third-party systems include:

  • Cisco 
  • Polycom
  • Lifesize 
  • Sony 
  • Microsoft Skype for Business and Surface Hub

View all supported devices.

Before you begin

To use Meet with third-party systems, you need to use the Google Workspace partner product Pexip for Google Meet.

  1. Sign up for the Pexip for Google Meet interoperability service at
  2. Configure Pexip to work with Google Meet.
  3. To let participants connect to Meet calls using Skype for Business, get a Skype for Business hostname from Pexip.

After you register, Pexip will contact you to complete the configuration.

Turn on Meet interoperability

Open all  |  Close all

Step 1: Go to the Google Meet settings in the Google Admin console
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in

  2. From the Admin console Home page, go to Appsand thenGoogle Workspaceand thenGoogle Meet.
  3. To apply the setting to everyone, leave the top organizational unit selected. Otherwise, select a child organizational unit or a configuration group.
Step 2: Add interoperability gateways
  1. In the Meet video settings section, click Gateways for interoperabilityand thenAdd Gateway.
  2. Enter a name as your own reference for the gateway and click Generate.
  3. Copy the gateway token to the clipboard and click Close.
  4. Send the gateway token to Pexip.
  5. On the Gateways for interoperability list, under Trusted devices, choose how you want third-party systems to connect to this gateway:
    • To require third-party systems to ask before connecting to a meeting, click Turn off "".
    • To allow third-party systems to connect without asking, click Turn on "".
Step 3: Turn on Meet interoperability
  1. In the Meet video settings section, click Interoperability.
  2. In the Interoperability section, check the Allow interoperability with other systems box.
  3. Choose the format for the meeting IDs used to join meetings:
    • Use long meeting IDs—Allow third-party systems to join automatically by SIP URI or when participants manually enter IDs into the system. Long IDs are added to calendar events and invites when events are created and can be used as long as the Meet link itself is available.
      Best practice: Long meeting IDs are recommended for most domains.
    •  Use short meeting IDs—Let participants join meetings using third-party systems by entering short IDs. When you choose this option, calendar events and invites contain a link to a page where participants get the short ID. Short IDs themselves are not added to calendar events and invites, SIP URIs are not generated, and calendar integrations don’t work. To join meetings using third-party systems, participants always need to enter the short IDs manually. Short IDs expire about 2 weeks after the last time they are used to join a meeting.
      Best practice: Short meeting IDs are recommended only for domains with existing interoperability configurations during transition periods while integrated joining options roll out.
    • Use both long and short meeting IDs—Provide both long IDs, which support calendar integrations, and short IDs, which support systems with limited-input functionality. Calendar events and invites show both long IDs and the link to the page where participants get short IDs. Participants can join meetings from supported third-party systems using a single touch. Participants can also join by manually entering long IDs (from events and invites) or short IDs (retrieved from a link in the calendar event or invite).
      Best practice: Using both long and short meeting IDs is recommended for domains that need to support both third-party systems with calendar integrations and systems with limited-input functionality, such as remote controls that make entering meeting IDs time-consuming or error-prone.
  4. Enter the gateway IP address, gateway hostname, and meeting ID prefix. External guests use these to join Meet calls from third-party systems. What you enter should match the settings of your Pexip Infinity gateway.
  5. (Optional) To set up interoperability for Skype for Business:  
    1. In the Interoperability with Skype for Business section, check the Provide an additional gateway for Skype for Business users box. 
    2. In the hostname field, enter the Pexip Skype for Business hostname. To get this hostname, contact Pexip.
  6. Click Save. If you configured an organizational unit or group, you might be able to Inherit or Override a parent organizational unit, or Unset a group.

    In most cases, existing third-party calendar integrations discover new SIP URIs for Meet, and upcoming Meet video calls appear on meeting lists automatically.

    To get joining information for Skype for Business, participants click More joining options on the calendar event or invite.

Information that Google shares with Pexip

When interoperability between Google Meet and third-party conference systems is turned on for your organization, Google shares with Pexip:

  • That interoperability is turned on for your Google Workspace domain and that an authentication token was created. Pexip requires this information for validation and compliance purposes.
  • Debugging and troubleshooting information, including call logs that contain participant IDs, meeting codes, and device information.
