(Basic) - no CallSignal if iPhone is locked

0 votes
Zoiper 3.14 on iOS 10.3.2
I try to get " Accout" work with your APP (free Version).
It works if iPhone is unlocked, but not it it is locked.
I enabled the following:
Settings -> incomming calls
   force background
   wi-fi keep alive
close and restart the APP, but still the same problem.
Zoiper Version: 3.14 / LibVersion: 2.8.40
How can i fix this ?

Please check the app : Background App Refresh and allow Zoiper to refresh.

That might help you.
