As an AppFoundry partner, we recommend always including both a DTMF timeout AND a no-input handler in every IVR menu.
The DTMF timeout fires when the caller presses a key but doesn’t press enough digits (e.g., they press ‘1’ but the menu expects ‘12’). The no-input handler fires when the caller doesn’t press anything at all. These are two completely separate Architect events.
In Five9 and NICE CXone, the IVR platforms have a single ‘no-input’ event that covers both scenarios.
Genesys Cloud Architect’s separation of DTMF timeout from no-input is more granular but also more error-prone. If you forget to handle the DTMF timeout, the flow hangs silently. Always design both paths, even if they route to the same destination.
From a forecasting perspective, high DTMF timeout rates indicate a confusing menu structure.
If 20% of callers are timing out at a specific menu, the menu is too long or the options are unclear. We track timeout rates per menu node in our Erlang model and flag any node exceeding 10% for redesign. This directly improves containment rates.
