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.
Claims20
A system for the application of security rules for specifying actions to be taken for the management and enforcement of policies related to the use of telecommunication services in an enterprise, said system comprising:
- a line sensor within the enterprise for:
- determining whether an incoming or an outgoing call is a voice, fax or data modem call;
- determining at least one attribute of either an incoming call or an outgoing call wherein said at least one attribute is selected from a list of attributes, including:
- call date, call time, call content, call duration, line identification, inbound number, outbound number dialed, dialing sequence, and DTMF;
- means for taking actions described in the security rules on either an incoming or an outgoing call conditioned on said determined type of call and said determined at least one attribute of an incoming or outgoing call.
A combination of a call type and call attribute sensor for use with telecommunications security rules enforcement system located in an enterprise, said combination comprising:
- a call type and call attribute sensor within the enterprise for:
- determining whether a call coming into the enterprise or directed out of the enterprise is a voice call, a fax call, or a call involving the transmission of data using a modem;
- determining at least one attribute of the either coming into the enterprise or directed out of the enterprise, said at least one attribute being selected from a list including:
- call date, call time, call content, call duration, line identification, inbound number, outbound number dialed, dialing sequence, and DTMF;
- means for taking telecommunications security actions based on the telecommunications security rules wherein said telecommunications security actions are conditioned on said determination if the call coming into the enterprise or directed out of the enterprise is a voice call, a fax call, or a call involving the transmission of data using a modem, and said determination of at least one attribute of the call either coming into the enterprise or directed out of the enterprise.
