A system and method of telephony resource management and security for monitoring and/or controlling and logging access between an enterprise's end-user stations and their respective circuits into the public switched telephone network (PSTN). One or more rules are defined which specify actions to be taken based upon at least one attribute of a call. Calls are detected and sensed to determine attributes associated with each call. Actions are then performed on selected calls based upon their attributes in accordance with the defined 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.

Virtual private switched telecommunications network

A system and method of telephony resource management and security for monitoring and/or controlling and logging access between an enterprise's end-user stations and their respective circuits into the public switched telephone network (PSTN). A set of security rules is defined for each of the extensions which specify actions to be taken based upon at least one attribute of the call on the extension. Calls are detected and sensed on the extensions to determine attributes associated with each call. Actions are then performed on selected calls based upon their attributes in accordance with the security rules defined for those extensions.

A system and method to provide secure access across the untrusted PSTN is described. The system and method utilizes telephony resources that can be initiated by a security policy defining actions to be taken based upon at least one attribute of the call, providing multi-tiered policy-based enforcement capabilities and visibility into security events.

Virtual private switched telephone network

A system and method for discriminating call content types for individual telephone lines at a plurality of user sites outside of a Public Switched Telephone Network (PSTN) is described. The system includes: a database containing security rules for each of a plurality of extensions, the rules specifying actions to be taken based upon a call content type of the call on the extension, wherein the call content type is determined at the user sites outside the PSTN; and a line sensor within the user sites outside the PSTN for determining the call content type of the call. The line sensor continuously checks the call content type to determine if the call content type changes.
