I had a customer call in this morning telling me his SX-200 is dropping all calls (room to room and inbound/outbound). The calls all connect but drop after 3 to 30 seconds. He says the console isn't showing any alarms. He's 70 miles away and my Mitel tech is on his honeymoon (at 55 years old) in Austria of all places. Ideas on what the problem might be? I'll be heading out in the morning (booked solid with a man out for two weeks)and have plenty of equipment in stock. Just don't have time for 2 hours of troubleshooting. I've worked on the 20s and 50s years ago but I'm an ESI, Nortel, Avaya guy. I don't want to load a backup on another system and swap the whole cabinet if it's just a BCC or MCC.
