Hi Mizutech

First of the bat your softphone for android just works, unlike some of the other softphones out there. Thank you!

Having said this I have found a couple of bugs you could say. First when I dial into a conference call when I work from home and mute my phones microphone all audio is muted including what I want to and need to hear, When I make calls at home it is via my WiFi network so lots of bandwidth. Secondly when I do make a call I don't hear the remote endpoint ringtone and I've gone through the settings unable to fine where I can enable this.

Thank you again.

Phone model HTC One X 
Android version 4.2.2
