Zoiper only rings when the screen is on but fails to wake up when the phone is asleep. I’ve disabled battery optimization, allowed background activity, and granted all permissions, yet I still only get a missed call notification instead of an actual ring. This makes the app unreliable for real-time calls. If you need push notifications or instant call wake-up, look elsewhere.

Hello, due to the specifics of the OS, Push Notification Service is needed to receive incoming calls when Zoiper works in the background. Push Notifications is offered as an optional in-app purchase. If you enabled it and still experience any issues, please contact us via the website to assist you further.

The app works well for me 90% of the time. My only feature request/improvement would be that it be more aggressive in attempting to re-register/re-connect after network changes. Many times the app is stuck at the "Registering..." status. If I exit the app and say no to "Do I want to continue receiving calls?" then re-open the app it'll re-register immediately.

Thank you for your feedback! We’re glad the app works well for you most of the time. We’ll look into improving re-registration after network changes to enhance the experience. Stay tuned for updates!

I've paid for the monthly subscription as well as the premium upgrade. I've been going several weeks now in which I am unable to answer any calls, they all go straight to voice mail. I contacted customer service, which you can only do by email, last week and the service worked great for two days. Now I'm back to the same issues as before. Would be nice to be able to actually talk to a real person @ tech support.
