To add more details, for now the Linphone application only supports push notifications with Linphone accounts.

This is because in our Flexisip SIP server we manage to send push notifications to the related devices when receiving a call/message. This probably isn't the case of your Asterisk server.

You can receive some calls/messages even without push notifications when some phones are locked for a very short time, but this isn't reliable. To keep things simple, push notification support on a server side is mandatory to receive messages/calls in real time on mobile devices.

In case you would want to create your own app derived from Linphone, we could eventually set up our Flexisip server as a Push Gateway, taking care of sending the push notifications while communicating with your backend server.

In any case, if you are interested for a commercial help, you can complete our Typeforms here (click on "Contact Us").

Dear Christian,


What you are describing here is a PUSH notification issue.


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


You can refer to the RFC 8599 and our Wiki article on this topic


Best regards,


Julien Favre-Bulle

Objet : [Linphone-developers] inphone disconnects from service at certain time on different mobile devices


Hello to all linphone team, it is a pleasure to write to you and ask for your help by this means.

I have had many problems running the linphone app on different mobile devices such as samsung or iphone

The error is the following
 I have installed the linphone app on iphone 6s to make and receive calls, the processes work fine as long as the app keeps it open when I minimize the app after approximately 4 minutes the service is disconnected from the Asterisk server. The same happens with another iphone 12, only on this device the app unlinks in about 10 minutes.

On my Cricket ovation 2 android phone it works great, even when the device is in sleep mode, and finally in another samsung A51 phone the same fault also occurs, the service is disconnected in approximately 4 minutes.


Now, when I turn the phone screen back on and reopen the application or select the app, the service relinks.

I consider that the failure is not due to the configuration of the sip extension, because in my phone the service is always active and linked to the asterisk server, but the other phone models that I mentioned is a matter of certain minutes where they are unlinked from the asterisk server

Please I need your help to solve this problem


Thanks so much
