[hylafax-users] "Failure to raise V.21 transmission carrier."

[Emery Guevremont <emery.guevremont@xxxxxxxxxxx>]

I've got a fax I'm trying to receive and on the 11th page transmission 
is stopped. When I go into the log file, I get this message:

"Failure to raise V.21 transmission carrier."

What exactly does this mean?
