Quality of audio with Opus and 48000 Hz Sampling are the main advantages excellent audio. Few suggestions for the UI. The default UI shows call history when you open the app, instead of sliding the side pane to reveal the contacts sub menu, can you please modify the UI, so that you have swipe-able card view, each card representing contacts, favourites (a must),call history. In all these cards you can have the icon to show the keypad. This will be user friendly and will make the app - layman friendly and will help in propagation of the app. Currently the menu is "nerd friendly" and not layman friendly. Similarly the incoming call screen needs a few glamour touch (check out zoiper for inspiration) there is no harm to be inspired :) Also the call screen needs tidying up with some smaller sized/proportionate icons with attractive colour scheme. I have an issue with the app when it is in a double NAT scenario trying to connect to the a sip server which also NATed. Calls gets established but there is no audio. Zoiper works with the same setup, so it is something Antisip app specific. The SIP server is behind a full cone NAT as per your other app which tests firewall and the sip client is behind a port restricted NAT. Could you throw some pointers as to what is the way to get this working

Thanks a lot for helpful comment. This app is more a demo rather than a user-friendly app... But I'll keep the comment in mind! About the no audio issue with double NAT, there is no supposed issue as long as the server relay RTP. You can contact me for more by email, if you wish to discuss further. Regards!

No-frills design, but very configurable and I found it quite reliable and reasonably battery friendly without the need to use FCM. Support for STUN/TURN, automatically switches to TCP when UDP is blocked. Wide range of audio codecs. The developer is very responsive and friendly. For me the best Android SIP client and I've tried many of them. Wish list: switch camera (front/back) when tapping own preview video, dark mode and please consider OpenSourcing so we can help. Many thanks for your work!

The recent 3cx update i have to register my sip account using capital letters but the app does not allow capital letters in the username of the sip settings. Also, there is no way to change the ringtone. You are stuck with a default one thats not very plesent. Update**** can you allow upper and lower case sip usernames? I can not use your app with the latest 3cx version. I will pay you to make this update.....

UPDATE: I have added a parameter to configure a "login" different than passw"username". This "login" used for authentication can contains "uppercase letters". Let me know if this is enough. I published the new release and it will be out as soon as google approve it! Regards.

What's new

HELP WANTED: please report any issue with translations (14 languages exists)

* LOGIN: add ability to configure a login with uppercase and different from username
* Change in the way we rotate the video
