A very useful SIP/VoIP client app. THANKS. Developer REMOVED UnNecessary FEATUREs in last/Updated version  like these: Devices & Apps Usage History Data Collection  Reading Sensitive Log Files  Read/Modify Contacts  etc Which were Violating Privacy-Rights. So NOW this APP is RESPECTING USER'S PRIVACY & other RIGHTS (comparatively more  than similar apps). So we r now increasing review Stars. As its improved & its a less-bloated & privacy-respecting app.
