Skype had a pretty expensive price tag, so of course Microsoft want to use it in Windows 8. During the Windows BUILD conference a feature was spotted that hints at built-in VoIP support.
Windows 8 Can Make Phone Calls
It should not come as a surprise but popular developer Long Zheng has published photos of the developer preview version of Windows 8 to show parts that prove the OS’ ability to make phone calls. The image on top shows a tile showing a missed call notification.
A second photo shown during the Windows Live demo unveiled that the “people” app was able to make calls and send out SMSs.
