Hi. Most times when we try to send a fax via Mac OS X 10.4's built-in fax software, the system rings the number and then just puts the fax on hold a few seconds later. When it re-tries 5 minutes later, the same thing happens. It's as if it's not waiting long enough for the fax machine at the other end to answer. If we listen in to the line, we can HEAR the receiving fax machine pick up but our Mac has already given up! We've tried it on two differnt iMacs (the old slot-loading ones) with the same results. Any idea what the problem might be? We can't find anywhere to set a preference to force the software to wait longer for the receiving fax to answer properly. Many thanks.
