Use a 4-pole change-over relay to switch the PRI connection either to the Asterisk box if it gets some sort of "heartbeat" signal from the computer (say, toggling one of the lines of a printer port, if the motherboard still has one), or the old PABX? You might have to do some mean, down and dirty low-level programming, to embed your heartbeat-generating code in Asterisk's idle loop; but the Source Code is out there, if you fancy the challenge ..... -- AJS Note: Originating address only accepts e-mail from list!
