Have a BCM 50 R3 with 4x16 expansion card. About 12 phones on the expansion card, found all of phones on the expansion card malfunctioning. Produces dial tone but cannot hang up. Cannot make a call, just obtain intercom dial tone. System is on a UPS and no power outage for 16 months thus far, I can tell from BCM Monitor. I change the power supply, issue persists, change the card and issue gone. Take card back to office, hook it up and no issue, 24 hours later no issue.
So I don't know for sure if the 4x16 card is bad or is there some other problem. Is this a HDD issue?
