ABSTRACT:
A system for securing telephony communications between an enterprise telephony endpoint and a remote telephony endpoint includes an isolated packet-based network, an exposed packet-based network, and an isolation device. The isolated packet-based network has a plurality of enterprise telephony endpoints. The exposed packet-based network is coupled to a public packet-based network and has a call management device that can receive an unsecured session request from a remote telephony endpoint coupled to the public packet-based network, determine that the unsecured session request identifies one of the enterprise telephony endpoints, and establish a media link between the remote telephony endpoint and the isolation device. The isolation device is coupled between the isolated packet-based network and the exposed packet-based network and can receive unsecured media associated with the media link, translate the unsecured media to reduce the likelihood of harmful code communicated by the remote telephony endpoint from reaching the identified enterprise telephony endpoint, and transmit the translated media to the isolated packet-based network.
