Re: [Linphone-developers] Notifications doesnt arrive on iOS after app goes to Background

[German Cancio]

Yuvi,

first of all, it would be beneficial to the community behind this mailing list 
to feed back if you were successful getting iOS to work, and what were the 
steps you did finally undertake to achieve this.

As for Android, there is indeed an option is the Linphone settings to have it 
running in the background. But you shouldn’t need to do so if you use Google’s 
Firebase push notification service to wake up Linphone. We do this at our site 
and it works fine. You may however need to disable battery saving settings on 
some smartphones, such as on Samsung ones. You can see in the client logs if 
push notifications are being received or not.

If you haven’t yet, you need to get some acquaintance with the Firebase push 
service. Have a look at the top-level README of the linphone-android gitlab 
repository. There are many instructions that can be googled on how to generate 
your own google-services.json. Then you will likely need to configure flexisip 
accordingly.

cheers, Germán
