Each case may be different, but in this case there's enough audio 
corruption going on that the modem is having difficulty training on the 
high-speed carrier.  The sender recognizes this, and eventually gives up.

So the question isn't really a HylaFAX one but rather one dealing with 
your Asterisk setup.  Why is the audio getting corrupted?

What kind of zaptel hardware are you using?

Thanks,

Lee.
