Dear Julien,


It’s possible not to use callkit on iOS.


Supporting push notifications has become compulsory since iOS 10 to receive incoming calls and messages when the app is not active in foreground.

To wake up a VoIP app when an incoming call or an incoming message is received, the server must send a push notification request to Apple PN server. For security reasons, Apple doesn't allow everybody to send push notifications to their servers. There are private keys and certificates to protect the whole process.

We have decided not to share Linphone’s push notification ID with third party services, and this is why the stock Linphone app can only receive push notifications sent from our service.


Not using Push Notification will restrict the usage of your app.

Hi Folks, sorry I did not spend time studying the source code on that point.


Is it possible not to use the callkit on Iphone iOS ?

I am trying to understand the implication of using callkit.


- This app will not use Voip Push.


- One concern would be that we may not want to share who we are calling with Apple.
