A branch office with a Merlin Magix system has recently shrunk in size, and is down to 2 (analog) trunk lines from 5. But now, when somebody makes an outgoing call 3 times out of 5 they get connected to a dead line. Of course, there are no manuals in sight... Is reconfiguring this simple enough that someone could offer step-by-step instructions to this Merlin neophyte? thanks//S
