Linphone is an open source app offering free audio/video calls and text messaging. With Linphone, you can be reachable at any time, even if the app is closed, with a WiFi or 3G/4G internet connection.

Linphone key features:
* High definition audio and video calls
* Audio conference calls with various participants
* Pictures and file sharing
* Linphone accounts reachable at any time, even if the app is closed (thanks to push notifications)
* Smart contact list to know whom among your friend is reachable thanks to Linphone
* Secure communication (encryption options)
* Compliant with a large number of SIP-compatible VoIP service providers allowing to reach everyone that has a "classic" phone line

Warning :
* Since IOS10, SIP connections in background are no longer allowed. Therefore, only Linphone accounts can receive calls when the app is closed, thanks to push notifications integrated within our server.
* It is possible that ending a GSM call to answer a Linphone call, through the double call screen, may lead to a loss of sound during the call. To get the sound back, you just need to pause and resume the call.

Linphone is available on the main mobile and desktop operating systems and offers various specific features for advanced users (codecs, transport standard, encryption options, DTMF...). For more information, see Linphone project website:

Note for developers and professionals:
Linphone can be rebranded and customized to meet specific needs. Contact Belledonne Communications for any specific development query.

Best of the free SIP phone apps


There is plenty to love and hate about this app, but the fact is this app has been the most reliable and regularly updated iOS SIP phones I have found. Thanks Linphone!!!

Unfortunately this new release consistently disconnects a Bluetooth headset at the moment a call is completed. Very annoying and confusing. You hear the ‘ringing’ while the destination is called but the second the other party picks up the headset is dropped.

Great SIP client that supports CallKit and PushKit


This SIP client is one of the few free apps to support iOS 10 CallKit, which treats VOIP calls like native phone calls and allows incoming calls to be answered without unlocking the phone. It's been working great on my iPhone and iPad.

It also supports PushKit for incoming call push notification but with a caveat- the SIP server must also support push notifications, and LinPhone's own SIP service seems to be the only free one to support it that I've found so far. So I had to set up an account with them and direct incoming calls to it to get full incoming call functionality. It's been working well, and I receive incoming calls even when the app isn't open. Battery life doesn't seem to be affected because PushKit is designed to be very power-efficient. Since iOS 10 eliminated support for background VOIP mode, PushKit is the only way to reliably receive incoming SIP calls on iOS 10.

One criticism I have is that LinPhone only uses its own ringtone instead of the system ringtone under CallKit, and there is no way to change it. On iOS 10, it would be useful to have the option to use the system ringtone and contact-specific custom ringtones that I set in my contacts app.

Very good


Works very well. I set it up using Nymgo sip provider. Difference with other sip phone apps is that the setting is not within the app, but you have to go to the settings of the iPhone. Very simple to set it up, very quick to load. Calls are connected very quickly. No frills, just a simple sip phone. Sound clarity is excellent when network connection is good. The light sensor is very sensitive in turning off the screen. To make it even better, would be to allow hands free connection using bluetooth, setting multiple sip accounts, and little beeps when pressing the number buttons.
