Abstract:
A telephone comprising:a speakerphone and a handset;a router having a first state and a second state and a microprocessor for selectively switching the router between the first and second state, and for selectively routing voice channels through said router;the router having first and second receive channel inputs, first and second transmit channel outputs, first and second acoustic outputs and at least one acoustic input, said acoustic input being connected to a transducer device for receiving sounds, said first acoustic output being connected to a transducer device for producing sounds through any one of said speakerphone and handset, and said second acoustic output being connected to a transducer device for producing sounds through the other of said speakerphone and handset;wherein when the router is in the first state a first receive path is defined by a first receive voice channel appearing at the first receive channel input being routed to the first acoustic output and a first transmit path is defined by a first transmit voice channel appearing at the acoustic input being routed Lo the first transmit channel output, and when the router is in the second state, in addition to the first receive path, a second receive path is defined by a second receive voice channel appearing at the second receive channel input being routed to the second acoustic output and a second transmit path instead of the first transmit path is defined by a second transmit voice channel appearing at the acoustic input being routed to the second transmit channel output.
