Listening to the audio recordings that you sent... the incoming audio is 
very poor.  I haven't yet passed that through a DSP test to see exactly 
how poor it is... if it's poor enough to not be able to decode at all... 
but it's very bad, and if the audio were to continue that way the fax 
won't come through.

What kind of setup is this?  What kind of PSTN interface are you using?

Thanks,
