Microsoft Discontinues Third-Party PBX Integration – What It Could Mean For You
On July 18, 2017, Microsoft announced that it will no longer support the use of Session Border Controllers (SBCs) and SIP integration to connect third-party PBXs/Telephony systems to Exchange Online Unified Messaging (UM). This means that Office 365 customers will no longer be able to directly connect third-party PBX systems with Exchange Online UM and will have to implement an alternative approach in order to provide voicemail or unified messaging to their users.
