What is the best way to program a fax did coming in on a PRI? I program the target lines to the analog port, but no matter what I do, I can't get the bcm to always generate a busy signal when the fax is in use. I have tried if busy, busy signal on the target line, DND on busy on the ext. I have even set up a hunt group with just the 1 fax member, and programmed if busy, busy signal. (This seems to be the best) But sometimes the call will still ring if the fax is in use. Thanks
