11th MVP Award Rewarded

I am actually on vacation, but as I sit here under the summer sun, toes in the pool and a cold drink within reach, I have been waiting for that email confirming that I’ve been awarded my 11th Microsoft MVP Award! As last year, I am being awarded in both the Teams and Copilot category. To say I’m humbled would be an understatement. Being part of the global Microsoft MVP community for over a decade now has been an incredible journey, filled with learning, sharing, speaking, and connecting with passionate technologists from every corner of the world. What is the Microsoft MVP Award? The Microsoft Most Valuable Professional (MVP) award is given to technology experts who share their knowledge and real-world expertise with communities. With fewer than 4,000 MVPs worldwide, it’s an honor to be part of such a vibrant and dedicated group. MVPs contribute through speaking engagements, writing, open-source contributions, and helping others online and offline. You can learn more about the progra...

So you think you have QOS enabled your Lync?

Well think again……

We had a very interesting workshop with one of Microsoft’s PFEs this week, and the focus of this workshop was deep diving into Voice in Lync 2013.

One important aspect of Voice is the implementation of CAC and QOS in the customer network, end to end. Followers of my blog will know I am strong supporter the end-to-end user experience. As a part of this, my strategy is to try to convince all my customers to implement both QOS and CAC (implementing one without the other could actually worsen the experience for the end user).

Newsflash: Some of work you do to implement these function could be “slightly” in vain. With Lync 2013 CU came Lync mobility with the possibility to join audio, video and conference through WLAN on the mobile device. This is great, and I use it a lot. However, as I have suspected, and now confirmed; Mobile clients do NOT support CAC (nor are there any QoS mechanisms on the devices).

A consequence of this is over-subscription of the capacity configured in your network, and all clients in the subnets where mobile clients exist can all suffer bad quality. Seeing how popular the mobility has become, this can turn out to be a challenge for many a administrator.

I still believe you should implement QOS and CAC wherever possible, but now we have to be aware of the mobile “surprise”, and try to calculate this into the rest of your scheme. Let’s all hope Microsoft will look for a way to enable QOS and CAC for mobile devices (They have for common area phones, so why not the mobile devices?). I did not get a clear list of all devices not supporting CAC, but I will post an update once I can get hold of such a list.


Anybody else with a thought on how to handle the subject, or even better, experience from a deployment where this has been an issue?
