I just wanted to check before making any assumptions. My customer has a dual cabinet 128 running SB 6.05C that had the power to his building cut for quite a few hours on a Saturday. When power came back on, the phones didn't. I went onsite to find all the card LEDs lit up OK, but the MPD was softly clicking at regular intervals. There is no display on the sets, I can't talk to it through the serial port, and when I call the lead number, all LEDs on all cards will go out momentarily, then come back on. This repeats if I let it ring additional times. I'm thinking MPD. All in favor say "Aye" or else a suggested next step?
