As Pedro mentioned, you'll see that the USR modems are the root of all 
fax evil.

The fact that you get an echo (AT+FTH=3 is echoed) indicates that the 
modem was reset.  HylaFAX didn't reset the modem, of course.  The modem 
did it on its own due to its internal firmware bugs.

A lot of people have seen this kind of problem with USR modems.  Some 
people have been able to work around the Class 1 firmware flaws in the 
USRs by not using AT+FTS/AT+FRS commands.  See 
/var/spool/hylafax/config/topic for examples on what to do to your 
config file to disable AT+FTS/AT+FRS.

But, a lot of people just solve the problem by getting new modems.
