Lync for Mac FAQ

My Skype for Business (SFB) for Mac is randomly dropping incoming and outgoing calls, and sometimes incoming calls go straight to voice mail without ringing. What is causing this?

Answer: The most recent version of SFB for Mac (version 14.05) is known to cause the behavior you described. If you or Microsoft auto-update upgraded your installation of SFB to version 14.05, UIT recommends you downgrade to version 14.04. For downgrading instructions, see UIT document SFB for Mac Downgrade – 14.05 to 14.04 [pdf].
