Dual tone multi frequency (DTMF) has an important use in many telecommunication systems, as many interactive voice response (IVR) systems use DTMF as a way for callers to navigate their menus. Therefore, Velox Prime apps also has a DMTF key feature.
This is how you use DMTF on your Velox Prime on Windows:
Step 1: Dial a number with an IVR system
Step 2: Navigate and click your mouse to DTMF icon:
Step 3: Press a key on your keyboard to this DTMF pad.
This should connect you to your selected menu on their IVR.
