So far so good

It was a little bit hard to setup as VoIPcloud not in the provider list, wasn’t sure if I needed to use TLS(SIP) or TLS(SIPS), anyway after a bit of trial and error I eventually got it to work. Seems reliable, I like that it stores credentials server side and sends push notifications so it even calls when the app is closed, which is something Linphone doesn’t do. Seems reliable so far, will update my review if it fails me.

Why is Call Integration isn't working? There's no Calling Account for Softphone to enable. I specifically purchased for this feature and it isn't working!!!

Worth the cost and love the app’s icon!

So many options and features to tweak everything from UI to noise suppression, codecs, countless others. Calls over Push notifications works. Very reliable, app/service never misses a beat.

Good app - but latest update killed connection

Been using for over a year and it’s great. Latest update killed connection and now stuck in registering. No idea how to fix

Works well

Works really well so far. Please add dark theme support to the app. The in call screen is already dark theme but the rest of the app is white. Thanks.

Fantastic app, worth the money

Love the app and really find it worth the money, but a few things would be worth looking into: - Custom Ringtones (the included ones are not that great, so the ability to add a short audio clip to play would be amazing) - making the App “universal” so it works well on iPads, this app would complete a proper portable office based on the device. The push that actually works is amazing and critical for proper use, and it’s fantastically stable.
