<p>In an example embodiment, a visual map of an Interactive voice response (IVR) system is provided to a client device such as a smartphone. The IVR map includes destinations and/or paths. When a user selects a destination and/or path, a client running on the client device generates the appropriate dual-tone multi-frequency (DTMF) tones for the selected destination and/or path, and sends the DTMF tones to the IVR system.</p> |
