System and method for providing communications services

A routing system for providing a communications service via a telecommunications network includes a switch communicatively coupled to a first interface, a second interface, and a third interface. Each interface is operable to relay an audio signal between a station and the switch. A signal processor is communicatively coupled to the switch and operable to monitor the audio signal for a trigger signal as the audio signal is relayed between the first interface and the second interface. The signal processor is further operable to selectively activate the switch upon detection of the trigger signal to communicably couple the third interface to the first interface and/or the second interface.
