Expanding Voice Attribution in Microsoft Teams Rooms

on
Microsoft Teams is enhancing the capabilities of   Intelligent Speaker Recognition , a feature that will identify and attribute speech to individual speakers in meeting transcripts. Initially this feature was exclusive to Microsoft Teams Rooms , but Microsoft has now announced it will extend this to  Bring Your Own Device ( BYOD ) settings as well.  To be able to benefit from this feature on BYOD rooms, users must have either a  Microsoft Teams Premium or a Copilot license. It is also important to make sure the meeting policy allows for recognition. This is configured with the  -RoomPeopleNameUserOverride switch, which can turn the feature off or allow for attribution and recognition. Users can set up their own profile in their own Teams Desktop App. Their profiles are stored within the company tenant. When joining a room, they must remember to sign into the meeting with their own app and selecting "RoomAudio" as the sound option to ensure their profile will b...

502_3 bad gateway IIS AAR RP for Lync

on
I encountered a "new" error message this week, as I was finalizing a Lync 2013 deployment for a customer. When I say new, it was new to me, as I had not seen this before. Everything was set up for remote access and federations, but certain features, such as mobility did not work right away. I decided to test the URL's from the outside, and was surprised to find the following error message:


This deployment was set up with a IIS ARR for reverse proxy. I searched for the 502 (502.3 to be exact) on forums and internet in general, but could not find any answer to my exact issue.

I verified firewall ports and connectivity was ok. I also checked the web sites on port 4443 and 8080 from a client inside, and saw no apparent errors.

I went through the deployment guide one more time (step by step), and discovered I had forgotten to import the internal CA ROOT to the Reverse Proxy machine. Once this was installed, it all worked just fine.

The reason I decided to write this post, is because the root cause was not very obvious to me (only after reading tracing logs and checking the step by step guide again, was I able to figure out the problem). And I wanted to write a reminder to myself, and maybe help somebody else if they happened to forget to import the ROOT CA.

The 502 "invalid response" can be a lot of things. Certificate error being one of them. Now I know.

For those looking for a guide to set this up, I have two links for you:
This is the one I used: http://uclobby.wordpress.com/2013/08/02/configuring-arr-for-lync-server/

And here is one from nexthop: http://blogs.technet.com/b/nexthop/archive/2013/02/19/using-iis-arr-as-a-reverse-proxy-for-lync-server-2013.aspx

I preferred the first one, as it was a more "general" rule to catch all. But it might not suit all scenarios. The one from nexthop is much more detailed, and will have you set up a rule for each URL.
