A system and method of telephony resource management and security for monitoring and/or controlling incoming and outgoing calls between an enterprise's end-user stations and a public circuit-switched network and/or a public packet-switched network. A security policy is made up of one or more rules designating at least one action to be performed based on at least one attribute of the incoming or outgoing call. Calls are detected and sensed on the line, trunk and/or cabling, and analyzed to determine attributes associated with each call. Actions are performed based upon the determined attributes, in accordance with the security policy rules.

Telephony security system

A system and method to provide secure access across the untrusted public switched telephone network is described. The system and method can be initiated by a security policy defining actions to be taken based upon at least one attribute of the call.

Encapsulation, compression, and encryption of PCM data

A system and method to provide secure communication across the untrusted public switched telephone network includes a set of rules in a security policy which are implemented by a virtual private switched telecommunications network (VPSTN). The VPSTN provides for intercepting voice calls and modifying their set-up to include a request for bearer capability to support a data call.
