## What is SIPhone?

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.
