Skype for Business - some similiarities to 'Corporate Midentity'

Some of the features offered include integrating Skype with the
Microsoft Outlook toolbar and a new auto-management tool that enables
group administrators to purchase Skype credits for one account and then
distribute them to employees, who can use them for Skype premium
services such as SkypeIn, SkypeOut, voicemail and third-party
conference calling.

Midentity for SMEs with distributable subscription SMS (and now with ClickDial credit).
