We are a systems reseller and wanted to offer an alternative to Bria so I'm testing Zoiper Premium. Have found the app clean and responsive so far but have a very annoying issue where the iphone fails to make any sound or wake up the disp[lay when receiving a call while the iphone is locked. Ive checked the IOS Notifications setting where 'Sound' is selected but makes no differance. We know the phone is receiving a call as if you click the IOS home button duirng the incoming call to wake up the didplay there is a notification showing on the screen as Zoiper Premium - Incoming call from ...
I've tested with Bria and it does wake up and ring with sound.
Please can you assist asap as we have a rollout next week and would like to use this app.
Thanks in advance
