Abstract:
1. A routing system for selectively bridging an operator station to a call between a calling station and a called station comprising: a switch; a first interface communicatively coupled to the switch and operable to communicably couple a first telephone circuit to the switch; a second interface communicatively coupled to the switch and operable to communicably couple a second telephone circuit to the switch; a third interface communicatively coupled to the switch and operable to communicably couple a third telephone circuit to the switch; and a signal processor communicatively coupled to the switch and operable to monitor an audio signal for a trigger signal as the audio signal is relayed between the first telephone circuit and the second telephone circuit over a communications link; wherein the signal processor is further operable to selectively activate the switch upon detection of the trigger signal to communicably couple the first interface to the third interface, wherein the first interface and the second interface remain configured to relay the audio signal over the communications link after the selective activation.
