Unspecified Transmit Phase D error...

[Alexandre Meissonnier <ameissonnier@dohle.com>]

Hi there!

>From time to time I get "Unspecified Transmit Phase D errors" while sending 
faxes. After one
or two  pages have been transmitted normally, the connection is interrupted 
after HylaFAX has
sent the MPS (More Pages Same Document) signal. Following attempts to send 
the same job
sometimes succeed, somtimes they fail again with the same error message. In 
the latter case,
the receiving machine gets 3 times the first two pages of the fax but never 
sees the rest of it.

First, I thought that this error was caused by bad phone lines, since it 
occurred mostly when
sending faxes from Germany to Poland.But it also happens on calls inside 
Germany, and faxes
to the same destinations using a paper fax machine work without problems.

Now I'd like to know:
- What does this message mean? and
- What can I do about it?

My modem is a ZyXEL 1496E.

Here's a sample logfile of such a job:
