I used mgetty-1.1.18-Sep11 and my modem definitely didn't answer any call. I
had this patch from an earlier revision of mgetty, so I applied it and it
did work. 
I agree that using an option is a much better solution. Gonna try that.

I should not have called it fix but workaround.

Good software engineers are expensive to pay ... unless you develop free
software.

c)
Oh, forgot it. Some fax machines have problems, if the page is too long.
There is an error after the first page then, so I cannot send more than one
page faxes. I adjusted the pagesize to the value I like: -g1728x2196.
I can add two header lines (cour25.pbm) and I get 1728x2289 which is what
most machines still accept.

I append the patch. Too bad, I also added an option to have a logo in the
upper right corner, so what you get is a combination of two patches. Sorry.
Anyway, the logo patch doesn't cause any problems, so you can also include
it, if you want to ...

I could have added a d)
d) I had to set dial-prefix ATX2D (sendfax.config) to disable BUSY detection. 
  My modem otherwise detects a BUSY(NO ANSWER, when an answering machine
  starts in the first place and the fax machine is not fast enough to take
  over the call.
