Integrating Microsoft Teams with Pexip Infinity
Pexip Cloud Video Interoperability (CVI) enables professional SIP and H.323 video conferencing systems to join Microsoft Teams as if they were native Microsoft clients.
It enables any video conferencing system to join Microsoft Teams meetings and allows authenticated systems to join as trusted participants without additional user interaction (i.e. lobby by-pass)
- H.323 & SIP room-based videoconferencing systems, including Cisco, Polycom, Lifesize, and others
- Browser-based video (WebRTC)
Third-party systems can connect to Teams meetings via the Infinity Gateway either via a Virtual Reception (IVR) or by dialing the conference directly.
You can also join Microsoft Teams meetings where that meeting is being hosted by an external third-party organization (even if the host’s organization has not enabled Pexip interoperability themselves) — this is referred to as "SIP Guest Join".

Integration features
Pexip Infinity is a Microsoft-certified video interoperability platform for Microsoft Teams. The Pexip Teams Connector is a Pexip application that is deployed in Microsoft Azure and is used to enable Cloud Video Interoperability (CVI) with Microsoft Teams. It handles all Teams communications and meeting requests from the Pexip Infinity platform and passes them on to the Microsoft Teams environment.
The key features of Pexip's CVI integration with Microsoft Teams are:
- Call in from any standards-based VTC system on SIP and H.323
- Lobby bypass for trusted endpoints, notifications and customizable waiting screen for untrusted VTC endpoints that are held in the lobby
- Choice of layouts for VTC participants, and spotlight support
- Audio-only participants are represented by their avatar from Exchange Online
- Raised hand, recording and transcription indicators
- Scheduled scaling to automatically scale up and down your call capacity at different times of the day
- Control and ownership of data
- Native VTC network resiliency and firewall traversal between private and public networks
- Bi-directional content sharing between VTCs and Microsoft Teams via Video-based Screen Sharing (VbSS)
- Synchronized mute/unmute control and status for VTCs
- Native scheduling via Outlook and Microsoft Teams client; join information is automatically added
- Tailored meeting invites with a customer-specific domain
- Full lobby and roster list control in the Teams client
Note that Microsoft Teams is inherently a dial-in service i.e. you can only dial from a third-party video system into Teams. You cannot dial out from Teams to a SIP, H.323 device etc — instead, you have to send the relevant joining instructions/invitation to the user of that device.
VTC user experience when joining a Teams conference
All VTC-based participants (SIP and H.323 devices) can either access the Teams conference via a customizable Virtual Reception service which prompts them to enter the Conference ID of the conference they want to join, or they may also be able to dial an address that takes them directly into a specific conference. Other software-based clients such as Skype for Business or Pexip's own Connect apps can also join via direct dial or via a Virtual Reception.
Pexip Infinity’s deployment model allows the use of a customer-specific domain such as teams@example.com for dialing the Teams Virtual Reception.
Alternative VTC dialing instructions can be provided that are customized to the company network and workflow such as:
- 123958530@vc.example.com
- 123958530@104.215.95.187
- 104.215.95.187##123958530
Participants using a Teams client join a Teams meeting as usual, and any gatewayed third-party participants can be seen and heard in the same way as any other directly-connected Teams clients in that meeting.
Authenticated, trusted VTCs that are located within the organization can join the conference directly, without any additional user interaction, whereas unauthenticated, untrusted external VTCs are admitted via the Teams lobby.

Admitting guest participants from the lobby
Any VTC participants that are already in the conference are notified when an untrusted VTC or guest Teams client enters the Teams lobby. They see an on-screen message and hear a knock-knock sound.
The meeting host can then use their Teams client to admit the waiting guests (the VTC system cannot admit guests).
If only some guests are admitted, the VTC's display refreshes the count of waiting users. If all guests are admitted, the VTC's display briefly shows a "The lobby is empty" message.
Audio participant avatars
Teams users who are logged in and have joined via audio-only are represented by an avatar (supplied by Exchange Online) within the VTC's conference layout. If no avatar is available, or it is a guest user from another organization, a substitute graphic is generated based on the participant’s initials.
Raised hand indicators
Notifications are shown to any VTC participants if a Teams participant raises their hand. An indicator slides out over the conference layout that identifies the participant with the raised hand and remains visible until the participant's hand is lowered.
Up to 3 indicators may be displayed, in the order that the hand was raised, with the oldest at the top. If there are more than 3 hands raised then the third indicator also shows the number of additional raised hands.
Note that you cannot use the Connect apps to lower the hand of a Teams participant.
Recording or transcribing a Teams conference
If a Microsoft Teams conference is recorded or transcribed, relevant audio prompts indicating that recording/transcribing has been started/stopped are played to callers who are gatewayed via Pexip Infinity into the conference

Migrating to Microsoft Teams from Skype for Business
Pexip Infinity works simultaneously with both Microsoft Teams and Skype for Business. This means that users can be enabled to use both platforms and they can be migrated from one platform to the other at your own pace. Interoperability into either platform is handled by the same single Pexip Infinity installation, and the same Conferencing Nodes.
For example you could provide a dial-in lobby address of:
- skype@example.com for interoperability into Skype for Business meetings
- teams@example.com for interoperability into Teams meetings
and
and then in each case the user would be directed to the appropriate Pexip Virtual Reception and would enter the appropriate conference ID for the relevant Microsoft meeting platform.
Microsoft Teams interoperability with Skype for Business
Microsoft Teams supports some level of interoperability with Skype for Business. This includes the ability to do a point-to-point voice and video call between Microsoft Teams and Skype for Business (depending on SfB/Teams setup, see https://docs.microsoft.com/en-us/microsoftteams/teams-and-skypeforbusiness-coexistence-and-interoperability#native-interop-experiences).
As Pexip supports native Skype for Business federation, it is technically possible to place a call between a Teams client (if the tenant is set up in a supported mode for SfB federation) and Pexip. However due to the limitations of this interoperability, in particular the lack of support for screen sharing / app sharing between Microsoft Teams and Skype for Business, this is not a use case that Pexip recommends or provides support for.
The certified interoperability for Microsoft Teams is for a Teams meeting to be scheduled (by an organization enabled for Pexip interoperability), and non-Teams compatible systems to dial in to the Teams meeting (see user experience below). This type of integration allows dual stream content sharing.
Streaming to Teams live events
You can use Pexip Infinity as an external RTMP encoder for your Teams live events, which means that you can stream video, audio and presentation content from your videoconferencing meeting room systems directly into the event.
See Using Pexip Infinity to stream from VTC systems into Microsoft Teams live events for more information.
