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.
