How do I make a Skype call using Siri on my iOS device?
With iOS 10 and SiriKit, you can call someone on Skype using the same voice commands you’re used to using already. Let’s say you’re trying to call Lisa Smith on Skype. If you have her Skype contact information saved on your iOS device, all you have to say is “Call Lisa on Skype.” If Siri needs clarification on the name of the contact, it may ask you to confirm the right one. After you tap the contact you want, your Skype call is initiated.
You need to have "Hey Siri" enabled on your iOS device to use this feature. Skype is not responsible for the content of external sites.
