Using Skype for Business/Lync to connect to videoconference rooms

You can use your Skype for Business/Lync client to make video calls to videoconference room systems and multi-point conferences on the IU Video Bridge.

Following is a selection of information about using Skype for Business/Lync for videoconferencing. For more, watch the video tutorial or see At IU, how can I create or join a videoconference?

Connecting to videoconferences

Following are some examples of possible Skype for Business/Lync video calls:

  • Connect to Video Bridge 231820: Enter 231820@vc.iu.edu, and then right-click the contact that appears and select Start a Video Call.
  • Connect to the videoconference room system called Bl-uits-cib-125: Enter Bl-uits-cib-125@vc.iu.edu, and then right-click the contact that appears and select Start a Video Call.
  • Connect to an IP address: Enter <ip address>@vc.iu.edu (replacing <ip address> with the IP address to which you want to connect), and then right-click the contact that appears and select Start a Video Call.
  • Connect to an E.164 number: Enter <e.164>@vc.iu.edu (replacing <e.164> with the E.164 number to which you want to connect), and then right-click the contact that appears and select Start a Video Call.
  • Connect to the copybird, a toy parrot that repeats what you say: Enter copybird@vc.iu.edu, and then right-click the contact that appears and select Start a Video Call. (This allows you to test your equipment.)

About the presence status of a conference or room

Presence status indicators are not always accurate for certain @vc.iu.edu addresses. For instance, a search for 23XXXX@vc.iu.edu will always show as offline, even though the call can be completed. On the other hand, green (Available) status merely indicates that the particular endpoint is registered to the vc.iu.edu gatekeeper/SIP registrar server. A system may display Available status when it is actually in a video call with another system.

Bandwidth and resolution

Because of a technical limitation, Skype for Business/Lync video calls to any @vc.iu.edu address have a maximum resolution of 320x240 CIF resolution.

Skype for Business/Lync video calls to any @vc.iu.edu address currently consume 384 Kbps bandwidth. You cannot modify this speed.

Sharing your screen

Participants using videoconferencing room systems can present their computer images to the videoconference.

Because of a software limitation, Skype for Business/Lync participants cannot present computer images to @vc.iu.edu addresses using the Skype for Business/Lync Share button.

Finding a videoconferencing room or Video Bridge

H.323 room systems are not part of Active Directory, and therefore do not appear in the Exchange Global Address List. To find the system name of the videoconferencing room system you wish to call or to reserve a videoconferencing room, see At IU, how do I reserve a videoconferencing room?

Inviting multiple contacts at once

In Skype for Business/Lync, to instantly create a multi-point call between individuals, you can select multiple contacts, and then right-click and select Start a Conference Call or Start a Video Call.

Unfortunately, an H.323 room system or a Video Bridge conference cannot join a conference call that you create using this method. If you need to mix Skype for Business/Lync and videoconference room systems in a call, use the IU Video Bridge.
