Since the Skype for Business server 2015 public release, one of the concerns that came up when upgrading existing Lync Server platforms to Skype for Business, is the support for SBAs. Microsoft issued a statement mentioning that the existing SBAs that are running with Lync server 2013 image, will be supported for Skype for Business till the hardware vendors come up with the Skype for Business image on their appliances.

Now, Sonus has announced that their newer software version V 5.0 for SBC 1000\2000 that supports Skype for Business Server, will be released on 28th of July 2015.
