What SIPhone can do
Mobile softphone
Make and receive calls directly from your smartphone – via your SIPONA telephony account, without the need for an additional telephone system.
It always rings
Incoming calls are reliably received: SIPhone rings just like a normal phone – even when the app is closed and the mobile is locked.
Contacts from SIPONA
Your contacts from SIPONA are available directly in the app – make a call with a single tap, without having to search for or manage numbers.
Easy registration
Log in using the username and password for your SIPONA user account – no manual SIP setup, no cryptic login details.
One phone number, everywhere
Stay reachable on the same number as at work – whether you’re in the office, working from home or on the move.
Secure connection
Encrypted telephony via TLS and SRTP. Operated by dus.net GmbH in Germany, without the use of a third-party cloud.
For iOS and Android
Native apps for iPhone and Android smartphones – featuring the familiar SIPONA user interface, available on the App Store and Google Play.
Signing up is that simple
Enter your SIPONA account username and password – that’s it. SIPhone automatically imports your telephony settings and contacts from SIPONA. No need to configure servers, ports or SIP profiles.
