Touchtone dialing on Palm?

It’s very obvious to me, and has been since I originally got a Palm device, that the address/phone book application should let you hold the palm up to a touch tone phone, and make the beeps to dial for you. Now that Palm devices have really nice speakers, this is even more obvious.

Yet I can’t find any software, at any price, that does this. The apps that claim to do touchtone dialing don’t actually do this through the speaker, but seem to assume that you have a modem attached, or that it’s a Treo or similar Palm/Phone thingy.

This is aggravating. Seems like a *very* simple thing, but I don’t have the Palm software fu to do it myself.
