The TopSec Phone app is a VoIP client for encrypted voice communications. For maximum security, voice recording, playback and encryption take place in a small wireless handset called “TopSec Mobile”.
The TopSec Mobile securely encrypts voice communications end-to-end on IP-based communications networks. Access to these communications networks is accomplished via Personal Hotspot of your iPhone.
The TopSec Phone app is used for call control and contact management.
To place and receive VoIP calls, both users must be registered on the same R&S®VoIP SERVER.
