In many calls, for example

ba2c1c2d-f92e-4f1f-b983-d33304b92546

, a DTMF key function call is made but the phone tree is not successfully navigated. We have tried this phone tree as humans and it works fine. Expected result: Press 4, reach next level of IVR / transferred to agent Actual result: Press 4, nothing happens, menu repeats

@Nathan I understand that you're experiencing issues with DTMF key function calls not successfully navigating the phone tree, despite it working fine when tested manually. To assist you better, could you please provide more details about how the DTMF function is being implemented in your calls? Are there any specific patterns or timings that you are using for the DTMF tones that might differ from the manual testing? Additionally, could you confirm if there are any error messages or logs that could give us more insight into the issue?

@Nathan for confirm can you check in twilio console because the digit 4 DTMF sound was generated. Twilio Call Sid: CA587ab6f1896e2eb8c502a85748577f2f
