I have a problem with the softphone clients on iOS. 3CX v15 Linux in cloud 3CX iPhone client Setup early December. About 2 weeks ago, calls push on mu iPhone stopped working. I didn't change a thing to my configuration. Everything works fine when app is open on phone, both incoming and outgoing calls. When phone and/or app on standby, there's no push, phone doesn't flinch. What happens: people calling hear the classic ringtone (so no busy or unavailable message), after 20 sec they get on VM. iPhone doesn't ring. When phone unlocked and in app, call comes through no problem. Problem is network independent (tried on 3 different wifi networks and 2 different 4G networks). Deleted and reinstalled the client. Deleted and reconfigured extension. Reprovisioned phone. Restarted 3CX server. Any advice or might this be a bug in the latest version of iphone client?
