CallKit integration for VoIP Apps

Most of us by now are accustomed to using the services of a third-party provider to make VoIP calls over desktops, laptops, and smartphones. But making VoIP over Native iOS apps was never a convenient task. In-fact Apple has completely restricted the use of VoIP push for any kind of background processing from iOS-13. Earlier developers were using VoIP push for making call (audio/video) notifications or some other processing in the background. Apple took this decision to avoid the overbearing process that was happening in the background. It was not only leading to disproportionately high consumption of resources but also a significant drain of battery capacity.

A typical VoIP call usually comes as a notification on one’s screen, and in order to receive it, the user needs to slide the notification and also type a passcode to receive, if locked. Burdensome! Isn’t it? Especially if compared to how a native app eases the same experience.

The solution to this comes with CallKit, which is a framework that is capable of elevating your third party VoIP app experience to a very intuitive one. You get the same rich, full- screen native call UI to accept and attend the calls. Once a call is accepted you also get a “Callback “option to initiate the same function (WebRTC) which you have used earlier. You can also set custom ringtones for your app that would be different from native calls ringtone.

Besides, if you are on a call in your app and you start getting native calls, you will be able to hold and swap the calls. It could be an audio call, facetime call or even another VoIP call. Even your call history will be stored in the call directory (missed, received, dialed calls and add in favorites). You can also make the call from Siri, Bluetooth and access the “Do not disturb” functionality.
