Discontinuation of support for Session Border Controllers in Exchange Online Unified Messaging

This highly impacts on organizations which are using third party enterprise telecomm systems. For those organizations, they've already invested on third party PBXs and SBCs and they are not as fast as to switch Skyype's enterprise voice for Exchhange online UM within a year. If they go with third party solutions like anynode, they will lose Exchange online UM features that areincluded in the Office 365 licnese bundle. MS should reconsider to support third party SBCs and/or postpone the discotinuation date to next couple of years.
