Reviews

Have bug.
Toshibo

New version 4.2 have bug with the clock and icons disappearing in the top of iPhone 11 Pro max with black bar.

Bad update
SharWill2

Since the new update Linphone won’t open on my IPad

Worthless
_m_a_x_

Loses the configuration information, does not stay registered in the background. Only good for placing calls.

Perfect at what it does
PHeede

This is a perfect app for anyone with a plain SIP VoIP account. It does exactly what it promises and delivers excellent call quality.

Secure voice and video have arrived!
SteeleNivenson

I've had a custom build with ZRTP for over a year but couldn't release it in the App Store. I used this update with ostel.co and confirmed secure calls work perfectly. Thanks for getting this published!

Crashes on iOS 8
x8c9s47d3r

This app worked fine on iOS 7. Now on iOS 8 it crashes and is unusable. I hope this can be fixed. Positive on iOS 7: best sound quality of all SIP clients I tried. On the negative side: smaller bugs, for instance contacts are sorted by first name.

Nice app, occasional bug
Djbryce

This app works as advertised. However, on the iPhone and iPad versions when you go to add a sip contact to your phone book it crashes the program.

Latest release
Sam57349

This release does not display properly on my iPad mini. The keypad only display the 1 2 3 keys and I can not find a way to initiate the call. The telephone icon is missing also. I used the previous release to test VOIP systems with great success, unfortunately it has't carried into this release. I will wait until the next release to award more stars.

Ipad woes
DJ Mickey

Same issues as first reviewer. Both iPad 2 and iPad mini in landscape mode only show partial keypad. If rotated to portrait it uses up only 3/4 of the screen, but does show full keypad. Chopped off on right side of screen however.
