Setting Up Any Skype for Business User to Give Busy on Busy


First of all you will need to have the Share Line Appearance application setup. See Click Here.

Prepare the Skype for Business/Lync User

  • Make sure that Exchange UM voicemail is NOT setup for this user. (we want the caller to get Busy on Busy, NOT voicemail, right?)
  • I might suggest to remove all delegates and team call members from the user you are going to enabled Busy on Busy, just to ensure no unexpected experience when enabling set-CsSlaConfiguration.

Now in Powershell we will very simply enable Busy on Busy for this user:
\>set-CsSlaConfiguration –Identity <skype4buser> –MaxNumberOfCalls 1 –BusyOption BusyOnBusy


Now place the 1st call to this user you just enabled Busy on Busy. This call should go through and connected. Stay connected on this call. (Placing the call on hold is fine, it is still considered a call to this user) and call this user again.

You will get a notice that the user is in another call.


This was tested on the Skype for Business client but not any other endpoints.

Also, this seems to work but I haven’t notice this officially mentioned as a supported scenario so try it out at your own risk, test it and give feedback if you find any problems with it.

Magewell USB Capture HDMI Review


The Magewell USB Capture HDMI can present the desktop/video output from one PC (or other HDMI output) to another PC as a USB Web camera (H264 UVC). You provide HDMI output to the Magewell HDMI input and it will send it to a PC as a USB webcam.

The device is truly plug and play. There is no drivers to install since the device uses standard H264 UVC webcam drivers.

Some things you will need for a typical Scenario

If you want to provide a Surface Pro 3 desktop/video to another PC as a USB webcam:

  • Surface Video Out/Mini DisplayPort to HDMI Adapter
  • HDMI cable

Surface video out/Mini DisplayPort to HDMI (F)


HDMI Cable (M)


Magewell HDMI IN


USB 3.0 to PC


Surface Pro 3 “Projecting” it’s desktop <-- MiniDisplayPort to HDMI –> <-- HDMI Cable --> Magewell USB Capture <—> USB Port on PC

Now in Skype for Business client select the Magewell device as the default video device. From here away the Magewell USB Capture HDMI can be used as any standard USB webcam. This includes presenting a PC Desktop to a Skype for Business Broadcast Meeting.

Some Skype for Business Meeting Video Quality Samples

1920x1200 On Project Device; Remote Skype for Business Meeting Participants view of Screen


2160x1440 On Project Device; Remote Skype for Business Meeting Participants view of Screen. (frankly I can’t see much difference in the quality from the lower resolution)


Skype for Business Meeting Screen Share Quality

IP Cam View Software Rendering: Quality

I tested directly displaying the USB input from the Magewell using IP Camera View software  from DeskShare (click here) and this software rendered the “projecting” PC’s desktop very clear. One caveat with the IP Camera View software is that I needed to manually set the Video Properties | Output Size to match the projecting PC as closely as possible. So this proves the Magewell is doing a good job, apparently Skype for Business is compressing or resizing the video a bit.

Here is a Video Capture Demo

(sorry for 360 video, youtube resizes it. but I think you can still get some idea of clearness)


In my testing I saw up to 108 degrees F.

Several things I noticed:


  • The device gets quite warm to the touch when receiving input
  • The display was unreadably fuzzy for first few seconds the PC was plugged in, then it got sharper.
  • Even at the sharpest PC video image is a bit fuzzy/unclear (see screen shots above) at least as compared to Skype for Business screen sharing. (see samples below)
  • This is likely a Skype for Business issue, but the video (PC screen) is reversed on the PC that has the device plugged in as a USB webcam
  • Highest natively support resolution is 1920x1200@60 (Surface Pro 3’s 2160 x 1440 is higher than that but did display)
  • Devices that did not work at all with the Magewell device (but did work fine with our large screen) as HDMI inputs
    • Microsoft Miracast HDMI adapter
    • Logitech ConferenceCam miracast HDMI output
    • Thinkpad T440S w/Windows 8.1 minidisplay port did not work
  • Devices that partially worked
    • Surface Pro 3/Windows 10: no audio, slow, jerky video
  • Devices that entirely worked
    • Surface 3/Windows 10


  • The device is another way to get smooth video AND audio into a Skype for Business meeting

The devices is ~$300 street price.

An alternative device option:

Take a Look at the Totally New Skype for Business for Mac

Today in Microsoft’s Skype for Business Broadcast prototypes of totally new Mac client were shown which gives an idea what new client might look like.

Interestingly it was noted that “Mac for Skype for Business will the most forward, modern locking client...PC client will catch-up…”. (hows that for vindicating Mac users?)

Another thing that was emphasized was “full bleed” video and content, which means video and content will use as much of the screen as possible. Buttons will “float” on top of video and content to give them all the monitor realestate possible.

See below:


Multiple Windows View


Meeting Experiences


Immersive Video


Immersive Presentations


To demonstrate that this is actually a working product Shawn showed a screen clip of an actually working product that he uses to “join meetings with”






Skype for Business User QuickTip #40: Easily See Presence & Call Contacts in Microsoft Excel Spreadsheet Columns

Ever get an Excel spreadsheet that has a column of contact phone numbers (or, even better yet, Skype for Business SIP URIs…) that you need to call? Calling though a Microsoft Excel spreadsheet list can be made a lot easier with a little work.

Skype for Business can handle URL beginning with SIP: or TEL:. We will leverage this by simply making 2 columns with the below formula’s. Replace the “A3” with the column/cell that has your SIP URI’s in it and likewise with the TEL:.

=HYPERLINK("sip:" & A3)

=HYPERLINK("tel:" & C3)


So first type in the formula and then drag the new formula down to the bottom of the column. Repeat for “tel:”

Now when you click on a SIP URI you will see the presence and have all Skype for Business modalities like IM, Call, Voicemail, Video, Collaborate available. With an additional click you can dial this Skype for Business contact. Or you can hover over the Contact name and see more information in the “Contact Card.” If your company has open federation enabled you will be surprised how many other contact have Skype for Business federation available!
