[Linphone-users] Iphone: Call when APP in background

[wf-keyword-linphone_users . e4e3c6]

Hello,

the Linphone iPhone app works perfectly for me when it is running in 
foreground. But when it runs in the background, i.e. some other app or 
the home screen is visible, I don't get alerted when a call comes in. 
But when I later bring the app to foreground, it starts ringing although 
the call was terminated long before.

Is there a way to configure Linphone to work like other softphones, e.g. 
3CX, which alerts me even if it is running in the background?

Regards
Werner
