Phase Errors & ZyXEL

[Matt White <whitem@bofh.usask.ca>]

Configuration:

Linux 2.0.27 (on a 486DX33)
HylaFax 4.0pl1
ZyXEL 1496E+ modem with 6.14 ROMs

When a fax is sent from certain fax machines and fax modems (one is a
USR Sportster 14400) to my fax server, the machines connect but fail
regularly with a Phase B error.  Here is a sample log:

Does anyone have any ideas?  Sending faxes works beautifully...
