The error basically means that the modem was unable to detect a V.21 carrier on the call. So if there really *is* a V.21 carrier (as you e-mail indicates that there is a fax machine calling), then something is wrong with the modem's detection of V.21 carriers. You will want to look into the modem manual, especially under the S-registers for some sensitivity settings with regards to these things. You may want to try different modems, also.

Hi all,
tryed to solve this with Hylafax 4.1.8.
We receive almost everything but there are problems with some fax
machines (two in particular from one of which the post below).
Are there any parameters to adjust to make receive faxes from all
machines?
Our modem is RCV288DPi Rev 05BA and we use it as class 1 fax machine.
Perhaps Fax1Timer or Fax2Timer may help?

Sorry for the long post.
