  • the present invention relates generally to a new telephony paradigm for placing a telephone call and, more particularly, to improved methodologies for placing a telephone call that is forwarded to another location.
  • Calling cards have been utilized by calling card holders to complete their telephone calls for countless millions of users around the world. There are many benefits for using a calling card over standard systems. For example, by using a calling card, the caller is able to negotiate a favorable per minute rate to complete their telephone calls. Further, besides the amount of minutes pre-purchased through a calling card plan, there is typically no long term obligation to continue with a calling card plan. In addition, a calling card holder is typically able to utilize any telephone within a general geographic area to complete their telephone call without incurring any toll charges to the originating telephone.
  • utilizing a calling card is often times more difficult than directly dialing the recipient's telephone number.
  • some calling card plans require the calling party to initially dial a general toll-free number to a calling card center. After calling the calling card center, the calling party enters their identification code, authenticating their identity, and then finally dials the recipient's telephone number. Further complicating the situation is that, if the calling card is lost or stolen, a person possessing the calling card is typically capable of using this calling card to complete their own telephone calls.
  • the systems, methods and apparatuses of the present invention combine the identity of the caller and the particular number dialed to properly connect the call.
  • Each caller-subscriber correlates a common bank of assigned incoming telephone numbers to personal dialing numbers of recipients.
  • Incoming calls from a particular caller-subscriber on a particular assigned incoming telephone number translates to a particular intended recipient, and the connection is made.

  • the present invention offers a complete solution by providing users with the ability to both establish a call to a recipient by dialing only a single telephone number and still have the call routed through an alternative gateway.
  • the present invention automates the authentication of the user and generally eliminates this cumbersome step by identifying the user, preferably, through the caller ID information of the originating telephone used for call placement.
  • Each user is preferably provided with a set of assigned telephone numbers that can be associated with a set of corresponding call recipient numbers so as to provide each user with the ability to place alternative network routed calls using a only a single telephone number, without requiring each user to actively participate in an authentication process or to dial a secondary number.
  • the aforementioned assigned telephone numbers are access telephone numbers for the alternative gateway that is responsive to calls designating as coming from the incoming assigned telephone numbers.
  • each user may be allowed to register a bank of numbers with the system so as to facilitate user identification based on the caller ID information received during the call establishment phase.
  • the user dials an assigned number (call identifier) that has been previously associated with a call recipient telephone number (recipient device identifier) from a device with a registered caller ID, upon receiving the incoming call, the system identifies the user based on the registered caller ID and then directs the call to a telephone (or other communication device) associated with the recipient telephone number.
  • the same assigned numbers may be used by a plurality of users for placement of calls to their respective call recipient, with the respective users and their respective lists differentiated from each other by virtue of the respective caller IDs, thereby permitting re -use of those assigned numbers.
