It turns out I was too optimistic.  It works *sometimes*.  It makes a
successful FAX transmission only about 20% of the time.  Usually it fails.
 A typical failure is in http://pastebin.freeswitch.org/20570

This is HylaFax running on the Freeswitch machine, using the SpanDSP
modems.  I'm calling a FAX number that's an analog PSTN line.  Can anybody
tell me what I'm doing wrong?
