Receiving a fax

["Jens Knoell" <jens@ing.twinwave.net>]

Following situation:
- Incoming call gets picked up by a human (i.e. picks up phone)
- Human realizes it's an incoming fax, and signals the linux box to receive
the fax

Problem: How do I force Linux to start receiving a fax since there is no
RING signal anymore (silly human picked up phone first)? I've tried with
mgetty, hylafax and efax - none of these seem to have any means of forcing
them to pick up the line and start receiving?

Anyone got a solution or idea to that particular problem? I kinda feel I
overlooked something trivial, just not sure what.

Thanks
Jens
