PrivateGSM Professional is an innovative software to encrypt your calls in a totally safe and legal way through the VoIP Internet Protocol. It needs to be configured on your own PrivateServer or it can auto-configure itself on PrivateWave's hosted server.

Once installed on mobile phones, PrivateGSM Professional gives you the option to encrypt calls between the users (i.e both caller and called need to have the software installed). Using PrivateGSM you can communicate easily and securely with your contacts.

Please keep in mind that there is no way to call numbers on a public switched telephone network (PSTN).
