Its fine

So far its been 2 years or so that I have been using the app. Only issue is with apple new iOS release it sometimes affect performance thus there is a need for phone reboot before it works properly. Lastly when I get an incoming call from my phone, it sends my current VoIP call into mute mode ahhhhhh!

So its ok for now
