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

["Ivan Petrov" <ivanp@xxxxxxxxxxxxx>]

Thanks for the response Darren,

You must be reading my mind :) I am going to throw Asterisk into the game as 
I intend to extend the process - to give the caller a chance to leave a 
voice mail instead of fax. I've even got one Digium telephony card (TDM04B - 
4 fxs ports) for that purpose, which I hope can do the job with Asterisk.

Right now I need quick solution for that exact situation I've described. I 
have almost managed to get Lee's solution to work. With latest hylafax 
(actually 4.2.3.1) I am able to playback the voice prompt read the DTMF, 
then receive the fax successfully. There are some new issues that are 
messing the things up(lost call ID1 and 2 fields by unknown reason so far), 
but I hope I will be able to resolve them.

Regards,
Ivan
