Questions and answers
Help with installation, SIP providers and everyday use.
Is bitCaller free?
Yes. The app is free, with no ads or analytics. You use your own SIP account; call and data charges depend on your provider.
What language does the app use?
The app interface is in Polish.
Which providers does bitCaller work with?
It works with practically any VoIP (SIP) provider. Enter your service details in the profile for another provider. otoTelefon is the current tested, predefined provider, with a preset profile and additional features.
Does bitCaller create a provider account?
You need an active SIP account from a provider. bitCaller lets you configure it and use it on Android.
Can I use multiple accounts and numbers?
You can add your SIP provider’s account. Multiple simultaneous accounts are supported for predefined providers. The predefined profile also supports extensions and assigned DDI numbers.
What does a predefined profile add?
Multiple simultaneous accounts, setup codes, named DDI numbers, identification of the number dialled by the caller, a colleague list, extensions, attended and blind transfers, and recording on your phone. PBX and DDI features require the appropriate service and provider configuration.
How does recording work?
Recording is available immediately and without an expiry date on the predefined profile, with no unlock code. Automatic recording is off by default. Recordings are saved on your phone. The provider of a managed account with a hidden password can disable recording or set an end date.
What happens when recording is disabled or expires?
You can still play existing recordings in call history, save copies or delete them. The restriction applies to new recordings, including automatic ones. The end date is shown in the app and applies until the end of that day in UTC.
What is a managed account?
The provider supplies an encrypted setup code with a hidden password. You review the settings and any recording policy before saving. Neither the app nor the setup page displays the password; changing it requires a new code from the provider. The code gives access to the account, so keep it confidential.
Does opening a QR code save the account immediately?
No. Review the provider profile, server, port and other details. Then confirm the changes or save and register a new account. You can cancel. If the code does not include a password, a new account will ask you to enter it.
The QR opens a web page instead of the app. What should I do?
Use the button to open the configuration in bitCaller. Check that you have the current version and that Android allows the app to open supported links. Codes with a SIP server and recording policy require the current app version. See Download for installation. Setup links open bitcaller.pl; that page is in Polish.
What happens to a second call?
In account settings, choose a busy signal or a notification. The default busy option rejects the next call with a busy signal. The notification option lets you reject it or end the current call and answer.
Do I have to share my contacts?
No. Permission allows caller names to be matched locally. Refusing it does not block calls or the system contact picker. You can turn off contact names in Settings.
What technical settings must my provider support?
The provider must support SIP over UDP and RTP audio. Use the server address and port they supply. Signalling and audio do not have transport encryption; stored credentials are protected by Android Keystore. See the privacy policy.
Can I use the app for emergency calls?
Use your phone’s system dialler for emergency calls.
I am a SIP provider. How can I get in touch?
Email zgloszenia@bitcaller.pl about testing your service and a predefined profile. Do not send passwords in an ordinary support message.
How do I report a bug?
In Settings, open the app information section and select the option to report a problem. Review the report before sending. Contact: zgloszenia@bitcaller.pl. Do not send passwords or setup codes.
