A new Skype job posting confirms what has been rumored before – Windows Phone will receive video calls over Skype. This functionality is going to be built into the Skype client that can be downloaded from Marketplace. We don’t know for sure if Microsoft will integrate Skype calls in the OS itself. This OS integration has previously been rumored to come in the spring 2012 update, currently called Tango.

Here’s the job description from Skype Careers:
