The present invention provides for selectively blocking outgoing calls based on blocking criteria configured by a telephony subscriber or representative thereof. When a call is initiated, blocking criteria associated with the telephony terminal from which the call is being initiated are used to determine whether the call should be blocked or allowed to continue. Once a determination is made, a telephony switch or telephony server supporting the telephony terminal either blocks the call or allows the call to continue as dictated by the blocking criteria. The blocking criteria may be applied to one or more telephony terminals. Further, the blocking criteria may be based on the party being called, time of day, day of week, financial authorization, type of call, or any combination thereof. The subscribers or representatives thereof can easily and efficiently configure the blocking criteria to control whether or not outgoing calls are blocked or allowed to continue. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention and illustrate the best mode of practicing the invention.
Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein.
It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
The present invention allows a telephony switch or like telephony server to selectively block calls being originated from a telephony terminal based on blocking criteria established by a subscriber or representative thereof.
The blocking criteria include one or more rules that define when to block call origination or allow a call to continue.
The blocking criteria can be readily configured by a subscriber or representative thereof, and may be used by the telephony switch or like telephony server to block or allow call origination.
For example, the blocking criteria may be configured by the subscriber or representative thereof via a web interface, telephony interface, or other interface facilitating human interaction.
The blocking criteria may be individually configured for a single telephony terminal, or for a group of telephony terminals supported by the same or different telephony switches or telephony servers.
The rules for the blocking criteria may be configured to block call originations from one or more telephony terminals based on the party being called, time of day, date, call type, such as 900 calls, long distance calls, or international calls, or the financial ability to incur charges from the telephony terminal.
For example, blocking criteria may be established to block calls to specific telephony addresses, such as directory numbers or uniform resources locators.
Alternatively, the blocking criteria may be configured to block all outgoing calls, except those directed to identified called parties
