StarLeaf offers a free service to provide interoperability for Skype for Business meetings. This service is called Medley.

This service is useful in the following two scenarios:

  • You want to join a Skype for Business meeting from 3rd-party video conferencing systems (for example, Cisco, Tandberg, Polycom, Lifesize, etc.)
  • You use Skype for Business and you want to invite participants who might use 3rd party video conferencing systems (for example, Cisco, Tandberg, Polycom, Lifesize, etc.)

You have been invited to a Skype for Business meeting

If you have been invited to a Skype for Business meeting, but you want to join from 3rd party video conferencing systems (for example, Cisco, Tandberg, Polycom, Lifesize, etc.):

  1. Forward the invite to skype@starleaf.com.
  2. You will receive an email that provides a dial-in address for your meeting. For example:
  3. Dial into the meeting on your 3rd-party video conferencing system using the dial-in address provided. You can do this up to 10 minutes before the start time of the conference.

When you join the meeting, you are placed in the lobby. Skype for Business requires the meeting owner to admit you to the meeting manually. If you are a meeting owner and you want to know how to do this, refer to the instructions in Allowing participants into your meeting.

You want to invite participants to your Skype for Business meeting

This service allows you to invite external people who use 3rd-party video conferencing systems into meetings hosted by Skype for Business. This service also allows you to invite internal 3rd-party video conferencing systems into your meetings. All you have to do is invite skype@starleaf.com to your meeting and StarLeaf will email you with the dialing details for you to pass on to your external participants.

  1. Schedule a Skype for Business meeting in the usual way, but add an additional participant with the email address: skype@starleaf.com.
    For example:
  2. You will receive an email that provides a dial-in address for your meeting. Pass this on to anyone who wants to join your meeting.
    For example:
  3. Participants can join the meeting up to 10 minutes before the start of the meeting.

Allowing participants into your meeting

Medley allows you to invite external people who use 3rd-party video conferencing systems to your meeting, but Skype for Business does not include these people directly in your meeting, by default. When an external user dials into your meeting, they are placed in the lobby. A notification banner appears on your meeting screen to say how many people are waiting in the lobby. To include any participants waiting in the lobby, simply click Admit on the notification banner.

Allowing participants to present

Not all meeting participants are allowed to present their screens straight away. To allow your participants to present, you need to follow the steps below to set the individual participant permissions, the permissions for only that meeting, or the global Skype for Business presenting permissions.

To give presenting permissions to an individual:

  1. Open the Participant pane.
  2. Right-click on the external participant, under Attendees, and click Make a Presenter from the dropdown menu.

To change the default presenting permissions for only that meeting:

  1. From within the Skype for Business meeting, click on the more options button in the lower-right corner and select Skype Meeting Options from the dropdown menu.
  2. In the Skype Meeting Options window, specify who is allowed to present in the meeting. Change the default option to Anyone (no restrictions) to allow external participants to present.

You can also access the Skype Meeting Options window if you are scheduling the meeting in Outlook using the StarLeaf Outlook plugin. The same option for presenter permissions is available, however, you can also choose to Remember Settings for future.

To change the global presenting permissions, you need to amend the meeting configuration settings as detailed in this Skype for Business library article .

Prerequisites and notes

This free service is available for all on-premise Skype for Business deployments and all Skype for Business Online deployments. Note that Skype for Business meetings are sometimes known as Microsoft AVMCU meetings. (A full integration service is also available for StarLeaf customers, refer to How to use StarLeaf with Microsoft AVMCU.)

The dial-in address for your meeting is unique to your meeting. The dial-in address will be in the format:
<7_digits>@skype.call.sl

  • To be able to join your conference, any external participants will need the ability to dial out from their own network onto the Internet. H.323 video systems have particular firewall traversal requirements that are described here
  • Your Skype for Business deployment must be configured to allow calls from the Internet. This means the deployment must be open-federated or you will need to follow the instructions in the relevant article below, remembering that the organization you need to federate with is skype.call.sl

StarLeaf Medley is a beta service. If you experience any problems, let us know (contact StarLeaf Support).
