flexfax: Problem receiving fax with ZyXEL Elite 2864

[Apiset Tananchai <aet@demo.ksc.co.th>]

Hi all,

I have problem receiving fax using HylaFax4.0 with ZyXEL Elite 2864 on my
Linux 2.0.32 (RedHat 4.2). There was no problem if the sender send only 1
page of fax. When try to send > 1 page I always got "Unspecified Phase C
error, including too much delay between TCF and +FDR command." Follow is
what in the log file:

Nov 27 22:37:36.70: [  726]: RECV FAX: end
Nov 27 22:37:36.70: [  726]: SESSION END

What configuration parameter do I have to change in order to reduce delay
between TCF and +FDR command? I can't seem to find in config(5F) man page.

Thanks,
