Integrating Google Hangouts Meet with Pexip Infinity
The Pexip Distributed Gateway provides any-to-any video interoperability with Google Hangouts Meet.
- H.323 & SIP room-based videoconferencing systems, including Cisco, Polycom, LifeSize, and others
- Microsoft Skype for Business and Lync
- Browser-based video (WebRTC / RTMP).
Third-party systems can connect to Hangouts Meet conferences via the Pexip Distributed Gateway either by dialing the conference directly or via a Virtual Reception (IVR).
The Hangouts Meet in-call features that are supported via the Pexip Distributed Gateway include:
- Active speaker switching
- Content sharing
- Recording indicator
- Bandwidth optimizations
See Configuring Pexip Infinity as a Google Hangouts Meet gateway for configuration instructions.
All participants receive the appropriate native user experience of the Hangouts Meet conference when there is a mix of direct and gatewayed third-party participants.
Users in your organization can schedule meetings as normal via their Calendar, and choose to enable Hangouts Meet conferencing within their event options. The joining instructions for internal and external VTC system interoperability are then automatically included in the Calendar invitation and event.
All calls are routed into the Hangouts Meet conference by means of the meeting code that is associated with that conference.
The meeting code is generated automatically and is 5 or more digits long, depending on the length of your preconfigured PIN prefix and the number of meetings you have previously held. For scheduled meetings, the meeting code is normally included in the meeting invitation (selectand look under — see the screenshot, right). This shows how to connect via standards-based video conferencing systems and Skype for Business users such as Windows/Mac clients, Surface Hubs and Skype Room Systems.
For ad hoc conferences the meeting codes are presented to the host when the meeting is initiated and are also available from theoption while in the conference.
After you have installed and performed the basic configuration of your Pexip Infinity platform, you have to link your Pexip platform to your G Suite account, so that it can route calls into your Hangouts Meet conferences. This is handled via access tokens, which are private codes that can be used by a third-party system, such as Pexip Infinity, to identify your account.
You can set up two types of access tokens in your G Suite account: a trusted and an untrusted token. You can use these two token types to control whether an endpoint that is routed via Pexip Infinity into a Hangouts Meet conference is automatically admitted into the conference, or whether an existing conference participant has to explicitly admit it into the conference. When you configure Pexip Infinity, you decide which type of token to associate with the access rules and dial patterns that allow devices to be routed into Hangouts Meet conferences.
Pexip Infinity also adds an additional layer of control by ensuring that only devices that are currently registered to Pexip Infinity are allowed directly into meetings.
In essence, when Pexip Infinity routes a call to Hangouts Meet, it provides three pieces of information:
- the meeting code (so that the endpoint joins the correct conference)
- the access token, which can be either a "trusted" or "untrusted" token
- a "domain member" flag, which indicates if the calling endpoint is registered to Pexip Infinity or not i.e. if it is a trusted endpoint from Pexip Infinity's perspective.
If the access token is a trusted token and the endpoint is registered to Pexip Infinity, then the device is automatically admitted into the conference.
In all other cases, the device has to be explicitly admitted into the conference (this takes the form of a popup dialog as shown right, which is displayed to all participants who are connected directly to the conference — note that "Pexip" will be replaced with your own company name). Any of those participants can then choose to allow (admit) or deny access.
See Configuring G Suite for Google Hangouts Meet integration and Configuring Pexip Infinity as a Google Hangouts Meet gateway for details about configuring access tokens, and Registering devices to Pexip Infinity for registration information.
Google Hangouts Meet does not support duo video / dual streams. This means that if any participant starts presenting, the other participants in the conference will only see the presentation stream, and not the video from that participant (their video is restored when they stop presenting).
For VTC participants who are accustomed to seeing dual streams. we recommend that if an external participant wants to present content or share their screen, they should use the native Hangouts Meet web client or a Connect client such as the web app to join the conference as a separate presentation-only participant, and then share their content from that device. This will provide a dedicated presentation participant/stream in addition to your video stream, and the other participants will be able to see both your video and your presentation.
