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

[yuvraj . narula]

Hi German

On Android ,  when linphone service is at background. It wakes up the app after 
two or three calls.

Means , when app is killed or not touched for few minutes, have to call the 
person twice , than other person get notifications for call.

Do we have to run the linphone service 24 hours at backeground, if yes which 
service/key/api would that be ?

Regards
Yuvi
