Thanks for sharing your call ID. To help diagnose why the DTMF tool didn't dial anything, could you check your Vapi dashboard's Call Logs for this call and let me know if there are any tool execution errors or if the DTMF tool was triggered at all? This will help pinpoint whether the issue is with tool configuration or something else. If you see any error messages or "no result returned" notes in the logs, please share them here.

Hi Mistermanu#000, To enhance IVR navigation using the DTMF tool, it is crucial to consider timing and formatting for effective interaction. Here are some best practices: 1. **Pauses in Input**: Insert pauses between digits to ensure the IVR registers each tone. For Vapi numbers, use

w

for 0.5s pause and

W

for 1s. Example:

1w2w3W4#

. 2. **Complete Menu Listening**: Wait for all options in the IVR menu to be spoken before responding. This prevents premature input sending. 3. **Input Retry**: If digits are missed, retry with slower inputs: - Fast:

123#

- Medium:

1w2w3#

- Slow:

1W2W3#

4. **Spoken Fallback**: If DTMF fails, try saying the option aloud. For more, see the detailed [IVR Navigation Guide](https://docs.vapi.ai/ivr-navigation).
