WARNING: using ZoiPer as a default dialer may interfere with dialing 911 emergency services.

Continues to works as expected. Good softphone. Update - I have used this app for the past 8 years. It works reliably. I have the pro version so I can have multiple phone numbers connected through it. It is my connection to my personal and business phone numbers. I like that all my VPN numbers send and receive text messages. When I am traveling, I connect through the hotspot on my cell phone and make and receive calls consistently. Recommend Zoiper.

just bought the pro version of the a few hours ago. However, the same SIP account, working on the free version, doesn't work on the pro version. When making phone call, the calling request gets timeout and gives internal server error every single time. Also, unable to receive calls using paid version but free version can. Switching to the free version, same time, same network, same device, the call gets through without any problem. Better stay with the free version. Can I request a refund?

Nothing but problems with this app. I have the premium version running in my S22 Ultra. It freezes up all of the time. It keeps ringing on my cell phone after a phone call has already been answered. Customers can not hear me speaking or there is a long delay before we can hear each other. A few times per week I have to force stop the app and restart it .
