Re: [hylafax-users] voice prompt playback before DTMF read?

["Darren Nickerson" <darren.nickerson@xxxxxxxx>]

Ivan,

HylaFAX's built-in DTMF handling has thus far assumed the DTMF will 
originate from automated agents (not people), so it's of limited use in the 
scenario you propose. As you have learned, Lee is working on extending that 
functionality and that may be something you wish to pursue with him.

Another very powerful way to do what you're trying to do is to add a second 
open source software product to the mix - Asterisk, the open source PBX. You 
can use it to build a simple IVR menu that plays an outgoing message and 
reacts to DTMF digits, connecting to call to HylaFAX and passing the 
necessary information along. Asterisk can also re-prompt the user if an 
incorrect response (or no response) was detected, and react differently 
according to caller-id, time of day etc. Once you have collected the DTMF 
you can then connect the call to your ZPX card and signal the DTMF to 
HylaFAX, or you can even eliminate the card altogether and use Lee's 
IAXModem.

This may be hitting a small problem with a large hammer and you may find a 
custom version of HylaFAX with additional DTMF capabilities meets your 
needs, but it's one of the more common ways to solve this problem today.

-Darren
