Exchange Unified Messaging

Microsoft Discontinuing SBC Support

Microsoft has announced that on December 1, 2019 they will discontinue support for using Session Border Controllers (SBC) to connect third-party PBX systems to Exchange Online Unified Messaging (UM). In light of Microsoft’s end-of-support announcement, many Microsoft customers are forced to seek an alternative Unified Messaging solution for Office 365 that can connect to their existing on-premises PBX.

Exchange 2019 Will No Longer Have UM

Microsoft has announced that Exchange Server 2019 will no longer include Unified Messaging support. This forces customers using an on-premises PBX, who wish to upgrade to Exchange 2019, to either switch to a third party UM solution or replace their PBX with Skype for Business Enterprise and start using Microsoft’s Cloud Voicemail solution.

XMedius provides Microsoft customers with a secure and flexible enterprise-class Unified Messaging solution that enables them to continue using their existing PBX or Skype for Business Server investments until they are ready to transition to the Cloud and Microsoft Phone System over time.
