  Nuxfon for iOS and Android 

 A phone, not a cloud 
======================

 Nuxfon is a SIP app that registers with the phone system you point it at. Nuxfon is not a phone system itself: without one, the app does not work. No account with us, no server of ours between your calls.

 What makes Nuxfon different 
-----------------------------

### Your phone system

FreePBX, Asterisk, FRITZ!Box or a provider of your choice. Nuxfon speaks SIP over UDP, TCP, TLS and WebSocket, and finds the right transport by itself. An existing phone system is a prerequisite, Nuxfon does not bring one.

### No account

You sign up nowhere. Credentials, call history and contacts stay on the device, the password in the keychain.

### Rings while closed

With a small wake-up service on your phone system, the phone rings even when the app is not open. Without that service, Nuxfon only rings while the app is running.

 [### Privacy

What stays on the device, what leaves it and where it goes. In full, with no analytics in between.
