I'm interested in building my own phone app for my Treo 600. One of the things I'd like to be able to do play the dailing tones as the user taps the numeric keys.
I see some traps in the HsPhoneTraps.h: PhnLibTrapPlayDTMF PhnLibTrapSendDTMF PhnLibTrapSendSilentDTMF etc. Those seem like what I would want to do, but I don't see any definition of the calls in the header. I do see some similar public calls in the TelephonyMgr.h (TelSpcPlayDTMF), but those seem like older APIs not relevant to the treo 600. I've also seen the helper style calls to dial a complete phone number, but I was looking for something with a little more control. Amongst my questions are: 1) Anybody know why some of the HsPhoneTraps.h are not public? 2) Anybody already figure out how to call them? 3) Am I barking up the wrong tree? Is there some other approved way to generate the tones when the phone is active? Thanks for any pointers. dK -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
