Emergency Calls: Your safety is important to us, always have more than one method of communication available to you. Please check and test with your SIP provider to confirm that emergency calling is available and functioning properly with your equipment.

Permissions: This app is based directly on the Android Dialer app and uses many of the same system wide permissions to provide you with matching experience. Where special permissions are needed to provide a better user experience as a non-system app, you will be prompted. You may at any time, revoke any permissions you had previously granted.

Privacy: Your privacy is important to us. Internal app data and diagnostics logs are retained only on your device and are not transmitted to us unless you explicitly contact us via the app and opt not to remove the attached data files as prompted in the email completed by you. You are invited to view our opensource code.

Battery Usage: The app maintains a highly-optimized background service to handle the SIP connection. Our in-house test devices often experience 24 to 72 hours standby, depending on usage, network conditions and settings.

Non-PSTN calls: This app only supports numeric telephone numbers.
