An integrated voice navigation system 40 is disclosed. The voice navigation system (40) includes a voice messaging system (44), a speech recognition system (46), a voice channel (50) and a control link (52). A caller is connected to the voice messaging system (44) via PSTN (42). The voice messaging system (44) is in turn connected to the speech recognition system (46). Specifically, the voice messaging system (44) and speech recognition system (46) are connected via both the voice channel (50) and the control link (52). The voice channel (50) provides an audio communications pathway between the caller and the speech recognition system (46), while the control link (52) provides an out-of-band communications pathway between the voice messaging system (44) and the speech recognition system (46).
