This app is good but if any phone call is connected while the skype call is on we can't hear back the voice after the phone call is disconnected. We have to disconnect the call and dial them back which is the only option. This is lingering and apps getting hanged sometimes though the network is good. Not sure what could be the reason. Voice call and call ring quality is not upto the mark. This works wonderfully in WhatsApp but lags here in skype
