StarLeaf supports calls into meetings hosted by a Microsoft AVMCU.

In this topic:

About Microsoft AVMCU

The following scenarios with a Microsoft AVMCU are supported:

  • From inside a Skype for Business meeting, you can add a StarLeaf registered endpoint as a participant. This scenario includes all StarLeaf and third-party endpoints that are registered to StarLeaf, and includes both on-premise Skype for Business and Skype for Business Online deployments. Refer to Add a StarLeaf endpoint from within a Skype for Business meeting
  • You can escalate a point-to-point Skype for Business call into an AVMCU meeting by ‘inviting’ a StarLeaf registered endpoint to that call. This scenario includes all StarLeaf and third-party endpoints that are registered to StarLeaf, and includes both on-premise Skype for Business and Skype for Business Online deployments. Refer to Escalate a point-to-point call to a Skype for Business meeting
  • You can cause the Join Now button on StarLeaf room systems to light for AVMCU scheduled meetings. This scenario includes both on-premise Skype for Business and Skype for Business Online deployments. Refer to Add a StarLeaf endpoint from within a Skype for Business meeting. This scenario does not include third-party endpoints that are registered to StarLeaf (and does not include StarLeaf Personal Telepresence or software clients)
  • H.323 endpoints can call into on-premise Skype for Business-hosted meetings by utilizing the Skype for Business IVR (Interactive Voice Response). Refer to Allow H.323 endpoints to call into on-premise Skype for Business-hosted meetings

Federation and firewall requirements

Skype for Business federation and firewall requirements apply. The Skype for Business deployment hosting the conference must either have open federation or be federated with the attendee’s subdomain.call.sl address. For more information on federation and firewall requirements, refer to one of: How to use StarLeaf with Skype for Business Server 2015, How to use StarLeaf with Lync Server 2013, How to use StarLeaf with Skype for Business Online.

For Skype for Business Online, you do not need to open any additional ports on the firewall. The ports that you have opened for your Skype for Business clients, to connect to the 365 server, are sufficient.

Add a StarLeaf endpoint from within a Skype for Business meeting

When you are in a Skype for Business meeting, you can add a StarLeaf endpoint to the meeting. In the conversation window, click the Add participant control in the top-right of the Skype for Business meeting:

Type the video address of the participant or room system; this must be in the format: subdomain.call.sl. This causes the AVMCU to dial out to that participant. When the participant answers the call, they are added to the Skype for Business meeting.

Escalate a point-to-point call to a Skype for Business meeting

When you are in a Skype for Business point-to-point call with a StarLeaf endpoint, you can escalate the call to a meeting with additional Skype for Business or StarLeaf participants. In the conversation window, click the Add participant control in the top-right of the Skype for Business call screen:

Type the video address of the participant or room system; this must be in the format: extension@subdomain.call.sl. This causes the AVMCU to escalate the call to a meeting and to dial out to that participant. When the participant answers the call, they are added to the Skype for Business meeting.

Invite a StarLeaf room system to a Skype for Business meeting

Schedule a Skype for Business meeting and invite the StarLeaf room system to that meeting. This invite must be sent to the room’s subdomain.call.sl video address. In the example below, we have invited london@example.call.sl:

Provided that the room system has been registered in the StarLeaf Portal with this video address, the green Join button lights for the scheduled meeting when it begins.

StarLeaf room systems can also receive forwarded invites. This means you can send the invite to any email address and that email recipient can forward it to a StarLeaf room system and that will also cause the Join button to light for that meeting.

You can also integrate your StarLeaf systems with MS Exchange room booking this allows users to simply add the room to the meeting rather than having to know the call.sl video address of a room). For more information, see Integrate MS Exchange room booking and StarLeaf.

If the meeting permissions have not been set up correctly, the StarLeaf room system may be directed to the lobby on joining the meeting. The meeting creator can add callers into the meeting from the lobby manually, or the permissions for the meeting can be edited in the Skype Meeting Options dialog. Under Permissions, set These people don’t have to wait in the lobby to Anyone (no restrictions).

By default, participants are not allowed to present or share their PC unless they are a “presenter” in the meeting. Permissions for presenting need to be set in the Skype Meeting Options under Permissions.

Allow H.323 endpoints to call into on-premise Skype for Business-hosted meetings

This method is for H.323 endpoints that are either registered with the StarLeaf Cloud or connected to a network that allows them to call to the StarLeaf Cloud. If your endpoints are not connected to the StarLeaf Cloud, you might need to configure your firewall; refer to Firewall configuration for calling from H.323 endpoints to StarLeaf.

You can allow H.323 endpoints to call into on-premise Skype for Business hosted meetings.

  1. Ensure that your Skype for Business server has the Conferencing Attendant service enabled. This provides your deployment with IVR capability (Interactive Voice Response).
  2. Create a SIP dial-in URI for Skype for Business-hosted meetings. Microsoft has provided instructions:
  3. Contact StarLeaf Technical Support and ask for a StarLeaf video address that redirects to that SIP URI. (H.323 endpoints dialing into a meeting will be redirected through StarLeaf where the necessary transcoding for the call will take place.)
  4. Modify your meeting-invite email template so that participants using H.323 endpoints will know to dial the StarLeaf video address. Microsoft has provided instructions for modifying email templates:
