SIPprime
Call with your own SIP account right on iPhone and iPad. Clear, fast and designed the Apple way. Your credentials stay on your device.
Keypad first
The home screen is the keypad with your account's status. One tap and the call is on.
Native calls
Incoming calls use the iOS call screen (CallKit), including on the Lock Screen.
Audio only
Landline quality with G.711, HD voice with G.722 and touch tones (DTMF). No video, no recording.
iPhone, iPad, iPhone Duo
Two columns on large screens and in landscape, and on iPhone Duo the layout keeps clear of the fold.
Private
No ads, no tracking. Passwords stay in your device's keychain.
Start for free
One account, calls, recents and contacts are free.
SIPprime Pro
One subscription unlocks every Pro feature: calls while the app is closed through our push server, multiple accounts, a ringtone per account, HD voice, encryption (TLS and SRTP), transfer and three-way conference.
CHF 2.00 per month or CHF 19.90 per year, each with 7 days free. The App Store sets prices in other currencies. The subscription renews automatically unless cancelled at least 24 hours before the end of the period in your Apple Account settings. Apple's Terms of Use (EULA) apply.
