[hsflinux] Current HSF modem does voice already

as you have mentioned, it is quite possible that they have modified the 
driver and used the digital call progress logging feature in order to 
record voice.

In the HSF driver package, there is a script named 'scripts/cnxtdcpd.in' 
which is used to receive the audio data from the kernel and send it to 
the sound card while the modem is connecting and waiting for the 
carrier. They probably modified this script in order to be able to 
record voice.

Note that this method is more like a hack than a real solution.

I would love to tell you how they did it but the code is encrypted and thus I have no access as to how they actually made this work. What I can tell you is that when it breaks.. which it does every now and then it reports that a modprobe on sound_slot_0 has fatal errors and the some Fax managment component is also having errors. So I guess it's a hack with some of these components. The solution uses PHP, that is all I know for sure.
