Zoiper Premium voip soft phone App Reviews

This is the best soft phone app I have used on my iPhone. Only problem is I have to restart it strikes in order for the audio to work on calls.

Stuck onsite at a client that had NO cell reception. This works great! And so easy to interact with my office.

I use this with my ec2 hosted instance of pbx in a flash Works great.

very useful and the best in voice applications

Doesnt provide a keypad during a call (theres an icon but its greyed out) for conference calls and menu systems. Which makes zoiper essentially useless for me. YMMV. PS: nags about access to my contact list and camera, which would be a nuisance if I was actually using the app.

I have an iPhone 6 Plus. You cant dial out from your contacts, if you click on a contact that you already have pre existing in your phones contacts list it will fail when dialing!! You cant copy and paste a number make the call, it will fail. You cant "Dial using Zoiper" when you come across a number on your email, browser, or anywhere else on your smartphone. When in background, if you dont use it for awhile it will stop. If you have a headset (I use Jabra 935 Pro DC) and you are finished with a call and you click the end call/make call button it wont end the call. If you click the same button to make a call, it wont work as that button is multifunctional. Also, I have purchased the premier version.

Quite often calls are not dialing and not connecting. I cannot save my contact in local Zoiper contact database. It wants to connect to all of my contacts which I do not want to allow. I also switched from free Zoiper to paid version and thought it will be better but no difference.

Its nice app with a user friendly features. I recommend to test it once.

Update... It has become a bit better since my original review below but there is still much work to do. It still shuts down and crashes after going between WiFi and LTE so its not reliable to receive calls. The audio will go out on calls. Please get these things fixed. It is behaving the same on my IPad on both IOS 8-9. End of my update, original review below... I hate to give this review because I believe that out of all of the VoIP apps, Zoiper has the most potential. I have noticed that over the last year, the app has gone down hill in both stability and audio performance. Stability wise, I can never get the app to stay active so I miss 9 out of 10 calls because it crashes or shuts down in the background so everyone just goes to my voice mail. Its very frustrating for those trying to get ahold of me. Performance wise, it will ether lock up in between my connections going from WiFi and LTE and vice versa. Also, the audio is bad and people cant understand me about half of the time. When it works, it works great, the rest of the time, people say my audio ether cuts out completely or I sound like a robot. I have tried every codec and Im using the ultimate IOS device which is the IPad Air 2 aka IPad 6. Something needs to change.since the last 2 updates, there wasnt an update for a year prior. Please fix these issues.

Great software

I upgraded to the premium version to utilize the phone book, However, it doesnt work. Ive been told by the company that it is fixed in the new version but Apple has not approved it for release. Other than that glitch I think its an awesome sip app.

Easy to use

This a very great app and on a high level. But only issue is i have problem when the app run in background, i dont received my calls. And the app makes also issue on my device so my device begin run very bad, like hangin and so on.

In the future if possible I want my call to be secured and with audio encryption setting.
