  • VC-to-DTMF interfacing system and method
    Patent number: 7092515
    Abstract: A voice command (VC)-to-DTMF interfacing system that allows existing DTMF-driven systems to be interacted with by a caller using voice commands. The VC-to-DTMF interfacing system translates the voice command from a caller into the DTMF codes which are then played through a port for receipt by the DTMF-driven system. In a first mode, the voice commands from the caller and the pre-recorded messages of the DTMF-driven system are echo cancelled. In a second mode, a voice message is directly streamed to the DTMF-driven system through an enabled port patch.
