The old GUI was'nt pretty but easier to use. I love the push technology thay is about all. If some one calls and I dont pick up it will just ring and ring even when the other party hung up the call. Please fix this issue
I have tested the app for a while now. Other apps like csipsimple or bria has have better audio quality
Callthrough and callback services cannot be configured on my Samsung s8. The menus there are garbled and unclickable.
Suddenly reads contacts when in background.
Excellent app. The best among 20 softphones tested in a period of 6 years, although on the expensive side. Push notifications work perfectly on both iOS and Android. By far the best Bluetooth support around. Highly customizable with nice new interface and better settings. However latest update makes it impossible to switch off vibration on ringing even when general setting is off on android 6.0.1. On android 7.0 I had to set vibration intensity to zero in order to get around this problem. Also when the app is closed it also exits and so no incoming calls may be received. Bugs that need to be fixed. Still gets 5 stars easily.
After to many hours trying and reviewing all the major sip apps, i've found this to be my 2nd equal sip phone app, Test phone is a Zenfone 3 running Android 7. Two accounts registered, used in a small business environment, interface is one of the best, good call quality, reliable but in priority order if it wants t be the best. 1] ringtone is timing out, i think it's not looping back to the start of tone 2] be able to switch off missed call notification. Now what i have found that makes this app work on the Zenfone 3, switch off battery optimization in settings for this app makes it reliable, even when using push. to switch off the video function on the call screen, move all the video codecs into disabled, to get the proximity sensor to work, check remember audio route in sound settings, and on the dialer screen when making a call choose receiver by pressing on the speaker image on the left side, no matter what app you use, make sure your codecs match you provider / pbx, this makes a huge difference to call quality, review updated 9/5/17
