Scenario: Call comes in and is answered on PC with Skype for Business client.  Using the client I hit the transfer button and type in a users name, right click and select "voicemail".  nothing happens.  Call is not transferred to voicemail. 

I have checked and exchange UM is answering and calls that are not answered are going to voicemail correctly. 

This only happens if the client is using the SfB skin.  If I change to the Lync 2013 the call will transfer to voicemail.  This is happening on multiple systems and with multiple installs at our customers. 

Has anyone resolved this issue? 

Hi,

There's a bug that was reported last week that addresses what you just described.
Further more, if you try to forward the call to any other person - it will also fail.

I believe this was already submitted to MS.

The workaround at the moment is to disable the S4B skin.
