UI needs work

The user interface needs some work. Tapping the menu button always takes about five attempts before I finally hit the exact spot. Also, the screen doesn’t fill my iPhone XR screen. Also, some of the icons are quite confusing. They aren’t very intuitive to know what they represent.

Awesome SIP client. But often - audio volume is low.

This is the best client in terms of voice quality. The only major issue I have with it - there is no option of audio volume preamplification. Often you can barely hear the person on the other side when you are in a somewhat noisy environment. If there would be configurable preamplification - I would give 5 stars!

Doesn’t work in background

This is awesome. Supports many configurable settings. However only way I can receive calls is have the app open on screen and iPhone cannot be in sleep or locked. I have notifications and background refresh on.
