Abstract: A call revenue enhancement system for a prison telephone system allows prisoners to make and initial call to a dialed number, and automatically prompts the called party to set up a credit card to be billed for future calls from the inmate. Additional phone numbers may also be specified to which the inmate may make calls which will be automatically charged to the credit card provided by the called party.

Abstract: A method and apparatus are provided for dynamically routing a plurality of simultaneous point-to-point communications through an array of repeating transceivers. Each repeating transceiver may simultaneously act as each of a transmitter of origin for one communication, a final receiver for a second communication, and a repeater for a plurality of other communications. When acting as a repeater, each transceiver applies programmed delays to information before re-transmitting, and these delays are programmed so as to route a communication through the array of transceivers along a designed path along which multiple re-transmissions from local repeating transceivers are received, aligned in time for constructive reinforcement, and retransmitted after dynamically programmable time delays.
