Ratings and reviews

I had zoiper for a long time. I had a problem that with push notifications paid for an enabled, the app would restart in a few minutes and would rapidly drain my battery (if I wanted incoming calls). I talked to support about it and they said it is because of server settings and they couldn't do anything. I switched to another voip client and the problem went away so it must be something about the client. Also, competition doesn't have a subscription for the push service but a one-time payment.

This app use to work well, but now it will not register...when it does, it doesn't stay registered for long, and either disconnects or stays in a constant state of registering. I have to close and restart the app for it to register. I use this for my business and pay for the pro version, annual fee. This has become completely unreliable. If the issue can not be fixed I will be forced to cancel my subscription and seek a better soft phone elsewhere. I don't know what changed, but it's worthless.

Used to work fine, now it doesn't. I generally get a ring in my phone through the app, but now there is NO WAY TO ANSWER THE CALL! My phone rings, I know it's the app, but no popup or notifications on the screen. I've tried to quickly open the app when a call is coming in but there's still no indication or way to answer! I was going to upgrade to get more reliable calls, but I don't think that would affect this issue.
