Does PuchiDen support touch-tone dialing (DTMF)?

Yes.

The keypad inside PuchiDen stays active during a call, not just before you connect. Tap the keypad icon mid-call, press your digits, and the system on the other end hears them exactly as if you were on a traditional landline. Card numbers, account references, conference PINs, voicemail navigation, "press 1 for English" menus: all of it works.

The reason this is worth mentioning at all is that a lot of internet-based calling apps quietly get touch tones wrong. They send the tones as ordinary audio, and the same compression that shrinks your voice for the network also smears the precise frequencies an IVR needs to decode "5" as "5". The bank's machine hears a smudge of noise and says "we did not catch that." PuchiDen routes the tones through our calling infrastructure in a way that survives the trip, whether you are on hotel WiFi in Lisbon, a cellular hotspot in Manila, or home ethernet in Tokyo.

A few things worth knowing:

• The digits you press (card numbers, PINs, booking references) are not stored, not logged, and not analysed by us. They pass through to the number you dialled and nowhere else. See our Privacy Policy page for the full picture.
• Wait for the IVR prompt to finish before pressing. Many older systems ignore tones played over the greeting.
• If a system tells you "we did not catch that," the problem is almost always tone delivery on the other side of the call. PuchiDen is built specifically to remove that as a cause.

The long-form version, including why a signalling standard from 1963 still runs essentially every bank phone tree in 2026 and what breaks when DTMF crosses borders, is in our blog post: Press 1 for English: The Hidden Language Your Phone Has Been Speaking Since 1963.
