SIPhone
VoIP calling for Sipona
Free · Designed for iPad. Not verified for macOS.
SIPhone is the SIP calling client for your Sipona line. Make encrypted HD-quality calls right from your iPhone — incoming calls ring natively through the iOS call UI, even when the screen is locked.
• Encrypted calling (TLS/SRTP) and HD voice
• Incoming calls via CallKit — ring in the background too (PushKit)
• Sign in with e-mail and password — that's it
• Call transfer, blind or attended
• Call waiting and switching between calls
• Phonebook & caller ID, per-call number withholding
• Interface in 24 EU languages
SIPhone is built on open-source software (baresip) — licenses are viewable in the app.
Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
• Calls now arrive reliably after a network change (Wi-Fi ↔ mobile, new IP address) – the app renews its connection itself.
• An ongoing call survives the network change.
• Call waiting: answer a second call, switch between the two calls and transfer – right from the iPhone call screen.
• Calls kept on hold for a long time no longer drop when resumed.
• Dialpad and line list show a single number; all numbers are in the line settings.
• Redial: with an empty field, the call button recalls the last dialed number.
• Keypad tones are audible again when dialing and during calls.
