Private branch exchange adapted for telemarketing

A private branch exchange for controlling a telephone terminal through a computer terminal associated with said telephone terminal, comprising:

• (a) a call handler;
• (b) registering means, associated with said call handler, for registering, in response to a registration signal transmitted from said telephone terminal or said computer terminal, said telephone terminal for said controlling;
• (c) directing means, associated with said call handler, for directing to a registration terminal interface, subsequent to said registering, first telephone call signaling messages for a signaling part of a physical terminal interface associated with said telephone terminal;
• (d) signaling means, associated with said registration terminal interface, for transmitting second telephone call signaling messages to said call handler, said second telephone call signaling messages replacing telephone call signaling messages received by said call handler from said signaling part in the absence of said registering;
• and
• (e) receiving means, associated with said registration terminal interface, for receiving command signals responsive to computer signals from said computer terminal, said command signals initiating said second telephone call signaling messages.

A private branch exchange for establishing a telephone call between a first telephone terminal and a second telephone terminal, comprising:

• (a) a call handler;
• (b) registering means, associated with said call handler, for registering, in response to a registration signal transmitted from said first telephone terminal or a computer terminal associated with said first telephone terminal, said first telephone terminal;
• (c) directing means, associated with said call handler, for directing to a registration terminal interface, subsequent to said registering, a call setup signal initiated from said second telephone terminal and intended for a signaling part of a physical terminal interface associated with said first telephone terminal;
• (d) call answer means, associated with said registration terminal interface, for transmitting a call answer signal from said registration terminal interface to said call handler;
• and
• (e) switching means for establishing, following receipt by said call handler of said call answer signal, a communication path between said first telephone terminal and said second telephone terminal for said telephone call.

A private branch exchange for establishing a telephone call between a first telephone terminal and a second telephone terminal, comprising:

• (a) a call handler;
• (b) receiving means, associated with said call handler, for receiving signals from a host computer identifying said first and second telephone terminals;
• (c) registering means, associated with said call handler, for registering, in response to a registration signal transmitted from said first telephone terminal or a computer terminal associated with said first telephone terminal, said first telephone terminal for control through a registration terminal interface;
• (d) first call setup means, associated with said call handler, for transmitting from said call handler a first call setup signal to a virtual terminal interface;
• (e) first call answer means, associated with said virtual terminal interface, for transmitting, without initiation by a corresponding signal from a telephone terminal and automatically in response to said first call setup signal, a first call answer signal from said virtual terminal interface to said call handler;
• (f) second call setup means, associated with said call handler, for transmitting from said call handler a second call setup signal to a destination interface associated with said second telephone terminal;
• (g) second call answer means, associated with said destination interface, for transmitting, upon initiation by a corresponding signal from said second telephone terminal, a second call answer signal from said destination interface to said call handler;
• (h) third call setup means, associated with said call handler, for transmitting from said call handler a third call setup signal to said registration terminal interface;
• (i) third call answer means, associated with said registration terminal interface, for transmitting a third call answer signal from said registration terminal interface to said call handler;
• and
• (j) switching means for establishing, following receipt by said call handler of said third call answer signal, a communication path between said first telephone terminal and said second telephone terminal for said telephone call.

A method for establishing a telephone call between a first telephone terminal and a second telephone terminal using a private branch exchange with a call handler, comprising:

• (a) receiving signals at said call handler from a host computer identifying said first and second telephone terminals;
• (b) transmitting from said call handler a first call setup signal to a virtual terminal interface;
• (c) transmitting, without initiation by a corresponding signal from a telephone terminal and automatically in response to said first call setup signal, a first call answer signal from said virtual terminal interface to said call handler;
• (d) transmitting from said call handler a second call setup signal to a destination interface associated with said second telephone terminal;
• (e) transmitting, upon initiation by a corresponding signal from said second telephone terminal, a second call answer signal from said destination interface to said call handler;
• (f) transmitting from said call handler a third call setup signal to a physical terminal interface associated with said first telephone terminal;
• (g) transmitting, upon initiation by a corresponding signal from said first telephone terminal, a third call answer signal from said physical terminal interface to said call handler;
• and
• (h) establishing, following receipt by said call handler of said third call answer signal, a communication path between said first telephone terminal and said second telephone terminal for said telephone call.

A method for controlling a telephone terminal with a computer terminal and a private branch exchange having a call handler, comprising:

• (a) registering at said call handler, in response to a registration signal transmitted from said telephone terminal or said computer terminal, said telephone terminal for said controlling;
• (b) directing to a registration terminal interface, subsequent to said registering, first telephone call signaling messages for a signaling part of a physical terminal interface associated with said telephone terminal;
• (c) transmitting second telephone call signaling messages, from said registration terminal interface to said call handler, in place of telephone call signaling messages received by said call handler from said signaling part in the absence of said registering;
• and
• (d) receiving at said registration terminal interface command signals responsive to computer signals from said computer terminal for initiating said second telephone call signaling messages.
