SIP - Acrobits Softphone is a SIP Client, not a VoIP service. You must have service with a VoIP provider that supports use on a standard SIP client to use it.


VoIP over 3G - Be aware that some mobile operators prohibit or restrict the use of VoIP over their network. They may prohibit the use of VoIP or impose additional fees when using VoIP over their network. By using the app over 3G, you agree to abide by any restrictions your cellular carrier imposes and agree that Acrobits will not be held responsible for any fees or liability imposed by your carrier for using the app over 3G network.


バージョン 5.9.25

-added support of iphone 12 (max, mini, pro)





Unshown account name that gets call

I have three accounts of IP Phone Service. In previous version, I can get which account get a call because the app shows it. But after updating, the app shows only phone number that I have call. Is it depends on my setting? If not, please fix it. I need this function because I have multi accounts.


The app should show account name automatically if there is more than one account. Please contact us at support@acrobits.net , I am sure we'll figure it out.



例: 番号A/着信番号or 番号B/着信番号



着信音設定が機能しません Ring tone setting does not work


I set the ringtone to the maximum in the application. However, if the iPhone's volume is the lowest, the ringtone does not sound.

CHINA MOBILEのSIMを入れていると設定からCallKitをONにするボタンが消えてCallKitを使うことができない。

CallKit can not be used in CHINA MOBILE's SIM
If CHINA MOBILE SIM is inserted, the button to turn on CallKit from setting disappears and you can not use CallKit.


We would love to offer CallKit to our Chinese users, but Chinese Ministry of Industry and Information Technology issued a regulation which prohibits CallKit use. This regulation is enforced by Apple and there is nothing we can do about it.
