About this app

Secure connection

Reliably reachable
• Incoming calls ring even when the screen is locked
• Calls are shown properly as a phone call by the system
• Battery-friendly thanks to push – no constant background service

Convenient calling
• Transfer calls – blind (straight through) or attended (consult first, then connect)
• Call waiting, a second call, and switching between calls
• Hold, mute, speaker, keypad (DTMF)
• Call your phone book and device contacts directly

Built for the EU
• User interface in 24 EU languages

Privacy

Note: SIPhone requires an active Sipona line. The app is a client for Sipona telephony and is not a standalone phone service.
