MicrosoftDiscontinuation of support for Session Border Controllers in Exchange Online Unified Messaging
If your company uses SBCs with Lync or Skype for Business to connect to Exchange UM for voicemail, you will be affected. You should begin planning now.

But if you're using Lync/Skype and connected with Exchange Online UM, you're most likely unaffected as this traffic will travel through your Edge server, and not a specific SBC (even if you use an SBC to connect to your phone company). This is mostly for third party PBXs who connect an SBC to the O365 SBCs to get to Exchange Online UM.
Correct, this only affects customers who use SBCs to connect to Office 365. Some companies have more than one PBX and may use SBCs for O365 connectivity, even when they have Lync/S4B in their environment.
Yes, my understanding is that we connect through the Edge for UM integration. The blog didn't specify Lync 2013 under the "not affected" bullet points, so I was just confirming whether it was specific only to S4B.
