| 1. A device for routing telephone calls along a least cost route originating from a first telephone to a second telephone having an associated telephone number via a network having a plurality of alternate communication switch paths corresponding to different carriers which can be chosen to route the call and normally providing a current to said first telephone when said first telephone is in use, comprising a housing forming an enclosure and comprising first jack means for connection to said first telephone and second jack means for connection to said network
switch means operatively connected to said first jack means for disconnecting said first telephone from said network during routing of a telephone call from said first telephone,
means operatively connected to said switch means for generating a current through said switch means to the first telephone[,]corresponding to a current provided by said network, when the first telephone is disconnected from said network by said switch means,
database means for storing billing rate parameters for determining a least cost communication path for call corresponding to said telephone number,
means operatively connected to said switch means for detecting and storing said telephone number originating from the first telephone,
means for addressing said database means for identifying a plurality of communication switch paths to said second telephone and the cost rate of each path,
means actuated subsequent to the detection of said telephone number originating from said first telephone for comparing the cost rate of each path so as to determine a least cost route, and
means operatively connected to said switch means and said second jack means for generating a number sequence corresponding to a desired carrier so that said call is routed through said second jack means to the selected communication path and carrier to establish a switched connection between said first telephone and said second telephone phone.
