TeleVPN® Call Shield provides enterprise-wide call confidentiality for voice, fax and modem calls made over the PSTN (Public Switched Telephone Network).

Communications through public infrastructure like the Internet and PSTN are at risk for interception, eavesdropping and/or vandalism. Accordingly, many organizations secure their data transmissions through the Internet with data VPNs (Virtual Private Networks). TeleVPN Call Shield adds similar protection to your voice network transmissions.

As opposed to competing voice encryption technologies that require separately deployed desktop devices, the TeleVPN System sits at the edge of the enterprise voice network to inexpensively encrypt communications from PBX-to-PBX. TeleVPN Call Shield provides a policy engine allowing policy-based encryption on a per-call basis, enforceable on an individual station, department or enterprise level.
