Welcome to Lync Server wiki library!
I am going to add content oriented to Lync Server implementation and my experience. Some information of cause you can find on so many UC (Unify Communication) blogs, some of them I didn't found and want to be shared to everybody.
I tried to find information about "How to Set Mikrotik DHCP Options 43 for vendor=MS-UC-Client?" and found just how to set DHCP Options for provisioning Lync IP Phones and how to set Mikrotik DHCP Options, but both in one store not. Lets see.
How to configure IIS ARR as Revers Proxy you can find without any problem but: how to verify configuration, how to resolve disconnecting error of Lync Mobile 2013 for 3 minutes and correct add more than 1 server to "Server Farm"? Lets see.
Snom 710 UC Edition successful connected to Microsoft Lync Server 2013 environment. But calling from Lync 2013 (desktop client) to snom got continuous "Connecting" and for incoming calls got error "No more media ports available". On forum https://forum.snom.com/index.php?showtopic=9421 found resolution adding route to Lync Server, in my case from Lync Edge Server to Snom subnet.
After I updated my Windows Phone 8.1 I decided to reset and connect it to my Microsoft Account. During the installation I selected options to use my SD for Photo, Music, Downloads and Application. After reinstall all applications I tried to configure and test them. And found that my Lync 2013 Mobile does not notified me about IM or calls, but before update Lync 2013 worked perfect. Lets see.
