Microsoft is bringing its Skype calling service to Amazon’s Alexa-enabled devices this week. Amazon’s Echo range will be able to access Skype’s basic calling, and hardware like the Echo Show will also include video calling support for Skype. This integration also lets Skype users call mobile and landlines using SkypeOut, and simply call contacts by saying “Alexa, call Tom on Skype” to activate a call.

The Skype and Alexa integration follows Microsoft’s increasingly close partnership with Amazon for Alexa, Cortana, and Xbox integration. The Xbox One now supports Alexa, and Amazon has launched its own Alexa Windows 10 app to bring the digital assistant to all PCs. Microsoft also just started selling Amazon’s Echo devices in its retail stores in the US this weekend.
