Re: Sharing One Line for Fax and Voice?

Sorry for jumping in, but how do those boxes work? Does the box pick

The one I use does keep the ring tone going while it listens for a fax tone.

Unfortunately, these boxes don't work for at least two types of incoming faxes:

  1. Some computer-generated faxes don't start generating a fax tone until after the line is answered and the ring tone stops. That was much more of an issue when I started using the box back in the late
80s, very few of those machines seem to be around by now.
  1. Some humans send all their faxes manually, and don't hit the "start" button until they hear the receiving fax answer and start squawking at them. So they try again and again, and leave hangup voicemail instead of sending the fax. Sometimes they can be convinced to change their ways, sometimes they can't. One client in particular has been sending faxes this way since they got their first machine in the 1970s, and they've trained the entire office to always send faxes on manual dial, so I get to talk to them more often than I otherwise would!
