Product Update: Push Notifications Now Support CallKit

This week, we are happy to introduce to you Push Notifications with CallKit for iOS.

If you are an iOS developer, you could simply send a call notification as a message, which would have been easily overlooked by any user. That may be an important call that you don't want the user to miss. The way to notify the user about an incoming call that he/she needs to answer is via Apple's CallKit.

Example of Push notification with CallKit Support

About Apple's CallKit


Apple's CallKit is the only choice for an iOS developer who wants to create a video or voice call with a native UI. CallKit, which was first introduced at WWDC session 203 in 2016, manages the iPhone's monitor for incoming and outgoing calls, dialing, third-party calling services like WhatsApp, and any Voice over Internet Protocol (VoIP) service.

For instance, it blends many of the functionality of VoIP apps with Apple's native interface. CallKit addresses and solves seemingly minor inconveniences including having to unlock your phone, go to the app, and press response, as well as having to drop VoIP calls for incoming cellular calls.

The architecture of CallKit was created to make VoIP app calls as smooth as possible. Users may use CallKit to make calls using Bluetooth, a Siri voice command, or Apple's native interface on iOS 10 and higher.

It also has a system for blocking spam calls, activating Do Not Disturb features, and communicating with other VoIP applications, allowing users to more efficiently manage incoming and outgoing calls and messages.

You have an option to pick calls directly via notifications which makes the user's experience much better than before.
