Abstract
A system and method of telephony security for controlling and logging access between an enterprise's end-user stations and their respective circuits into the public switched telephone network (PSTN). A security policy, i.e., a set of security rules, are defined for each of the extensions, the rules specifying 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.
