Hello,

If your iOS devices are updated to iOS above version 11.x, then this issue is known and we are working to resolve it. iOS is putting Zoiper to sleep when it is on background, the previous workarounds that we used seem to work less reliably now. Additionally soon we should also offer PUSH notifications to completely resolve this.

We are sorry for any caused inconvenience.

Hi there,

I am still getting this issue as of today. May I know if it is related? Don't think there's any mechanism to "wake" up the sleeping iPhone when its moved into hibernation mode. I am using TCP with keepalives at 20seconds. (qualify=20000).

frustrated!

tried push on iphone 8 with IOS 11, didn't work. and get worse: after turning push on, no incoming call again even not close zoiper.

afterwards zoiper couldn't startup,and closed itself.

so we need to pay again for this feature ? why is it not included in premium version ?

commented Sep 18, 2018 by synlau (100 points)

@Synlau, it is subscription based and is an addition to the other premium features. You can use it only if you want it.

@castro, you can use the contact form on our website to report the crash.

has this issue been resolved??

commented Nov 14, 2018 by sharon (210 points)

You can now enable PUSH notificaitions. There is no other way for Zoiper to work on background on iOS devices.
