There are plenty of VOIP apps around, and they all have their own dialers and interfaces which is fine, but sometimes it can be a little confusing when you hear your Phone ringing and see a different phone UI compared to the one that your operating system uses. Apple has tried to remedy this with CallKit, and the latest version of Skype will be taking advantage of that.
Announced on the Skype Blog, “Additionally, because Skype takes advantage of CallKit within iOS 10, incoming Skype calls will now show up just like regular calls. This will make it easy to switch between or answer Skype and regular calls using the built-in iOS functionality you are already used to.”
This feature is only available for regular Skype users, but the company states that they will be expanding it to Skype for Business in October. “Starting in October, we’re also extending this CallKit functionality to our Skype for Business iOS apps, giving business users the same great calling experience.”
