The first server update for Skype for Business Server 2015 was released 19th of June:

The update can be downloaded here Skype4B CU1

The new version after the update is 6.0.9319.55:Skype4B_CU1

A customer contacted me with a request to look into a problem regarding duplicate numbers in the Lync client contact card. When a Lync user would call a colleague, the numbers displayed in the list would be duplicates with normal eight digits and the same number with a + sign in front. After some digging in AD, Exchange and Lync without figuring out where this number came from, I kind of stumbled across the solution.

I created a normalization rule that normalized all numbers starting with a +, removing the + and adding +47(for Norway):

RegEx Matching pattern ^\+(\d{8})$ (for Norwegian eight digit phone numbers, replace with your own digit length), Translating rule +47$1 (Norwegian national prefix, replace with your own).

This change in normalization for workaround purposes turned out to be a valid solution to remediate the problem with duplicate numbers. Seems like Lync is collapsing the numbers based on the newly created normalization rule, thereby de-cluttering the number lookup in the contact card and call rooster.

Maybe this is documented somewhere in MS documentation, but if not, here’s how to fix the problem if you stumble across it :)

Comments greatly appreciated.

As you all know, the Skype4B server upgrade can be done as an in-place upgrade from Lync 2013. However, there are things to concider. 

If the server is a Lync 2010 server, there is no way to do an in-place upgrade. Migration is the only way. 

Lync 2013 supports the in-place upgrade as long as you can schedule downtime because the services are removed during the process. 

When it comes to the server OS, you would want to concider upgrading the server if you’re on WinSrv 2008 or 2008R2. The Skype4B server install will upgrade windows fabric to the latest version, but only on 2008R2.

Recommendation: Win2008 or 2008R2 should be upgraded to 2012R2.

Implication: The upgrade process to Skype4B will have to be done as a migration if your servers are on Win2008 or Win2008R2.

For some time now, I’ve had the pleasure of using the Jabra Evolve 65 MS Stereo headset on my Lync client. I would like to share my experiences in this blogpost.

As you all probably know, the importance of proper end user equipment in Lync is vital for user adoption. All Lync users should have access to a Lync certified headset and camera. Without such equipment, the user experience is most likely to be degraded and the user adoption of Lync as a communication solution will suffer.

The Jabra Evolve series is a new series of headsets from Jabra which focuses on design and audio quality. The models comes in both stereo and mono editions, and ranges from the top model Evolve 80 UC with active noise cancelling down to Evolve 20 which is the entry model. All models can be viewed here.

My choice of the Evolve 65 MS Stereo was based on portability and the option to be able to work wirelessly via Bluetooth connected to both my Lync client and cell phone. The headset comes in a pouch and is provided with a USB cable for connecting to the PC/Mac and a USB dongle for Bluetooth connection(if your computer doesn’t have Bluetooth integrated).

Connecting the headset is very easy, just turn it on and push the power button all the way up and hold until instructed on how to locate Bluetooth device.

Once connected, you can start using the headset for Lync, Skype and music.

Personally, I like the concept of being able to play music from my computer while working and at the same time being able to answer my incoming calls in one device. The Jabra Evolve 80 MS Stereo is probably better if you have to “zone out” an focus deeply in a matter which requires your absolute attention, but the Jabra Evolve 65 MS Stereo works absolutely to my expectations in my regular day to day tasks.

This picture shows the schematics of the headset. The microphone boom-arm can be flipped to either side as it has a 270 degree adjustment.

The busylight indicator can be turned on and off manually, allowing you to signal to you co-workers that you are busy and don’t want to be disturbed.

Some organisations may have limitations in what kind of equipment the users are allowed to purchase in terms of prices etc. However, it’s of great importance that the equipment is of a quality that allows for good end user experience regarding audio and video. The Jabra Evolve 65 MS Stereo is by my opinion one of the best alternatives when it comes to headsets, and the price should not intimidate anyone.

My recommendation when it comes to Lync Headsets.

The stats helper monkeys prepared a 2014 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 17,000 times in 2014. If it were a concert at Sydney Opera House, it would take about 6 sold-out performances for that many people to see it.
