Ratings and Reviews
It is very good app but recently (maybe after upgrade to iOS 12 or updating my app) I have 2 big problem
1) sudden disconnect while talking (without any network problem)
2) transfer not working at most time!
Developer Response ,
I am sorry you are having problems with our app. We'll be glad to troubleshoot, please contact us at firstname.lastname@example.org and we'll do our best to resolve your issues.
Excellent app with a killer feature
This is a great app for family or enterprise use. Great voice quality, flexible options, nice integration with iPhone (and iPad), lovely user interface.
And: After some plowing through Acrobits’ wiki and scratching my head a little, I found it supports external provisioning. That’s wonderful: you can set up simple .xml provisioning profiles on a web server (or even in Dropbox’s public web folder) and give your users a click-link that, when clicked on their iDevice, will automatically set this application up. I’ve encouraged Acrobits to improve the description of how to do this, but if I figured it out you probably can too.
Really great app, and well worth the small amount of money it costs… especially considering the massive savings VoIP brings!
UPDATE: after several years I remain delighted with this app. Call quality, ease of use, iPhone-worthy design... first class stuff.

Thank you very much for your kind words!
The best Softphone Sips app out there
I was looking for a softphone app to use with my new voip provider, and this was recommended to me.
Well what an app it is! There are lots of features including call recording, and what i love is I can have more than one line / provider configured with it!
Now I did have some questions / issues and reach out to the developer using there help desk ticket systems and they answer right away and the reply’s were great! Giving me the information I needed to get it sorted!
Thanks again guys and keep the great work up!
Quality of sound is amazing!
