I have a Mitel pbx, 3.5 floppy type, that has a bug in it. On the superset4 it will intermittently by itself goes off hook to speaker phone and redial the last number it has called. This is happening on diffent supersets. This Mitel has a 2 cabinets one analog bay 4 and 5, the other digital bay 1,2. Any thoughts on what is going on. Thanks

Are the SS4's on a digital COV card or older superset card? Or are they spread throughout the older analog bays & digital bays?

spread out

Right now to stop the SS4 from calling I have taken away the redial function (system option) on the SS4. Another tech thought the data base might be corrupted and I might have to reprogram the database from scratch.

Correction, I know some are on the digital side but will have to see if some are acting up on the analog side. Have you seen this problem before?

Not this exact issue, but supersets do strange things when software or hardware starts going bad. Have you rebooted the system? Have you done a backup recently? Restting the old systems that utilize the floppies can be a little scarry.

Last night we did a backup and rebooted the PBX. This morning we got calls again that the PBX was acting up. Last year we had the same issue only on a few SS4 and bandaid that issue by changing the COS to select key to dial out only . Now somehow it is going off hook and selecting the key and redial. So the ghost now knows how to select key. I can change out the main control board but cannot see how that would cause that problem.Really weird.

I had the exact issue years ago..same setup with analog and digital cabinets. One by one I eliminated the SS cards on the analog side which resolved the issue. real crazy though. Hope you have spare slots on the digital cabinet to replace the analog SS cards.

So do you think the database is corrupted? I have some trunk cards in the digital side that I could convert to the analog side to make room for the COV cards but I hate to just bandaid the problem.
In the past the analog SS4 had a noise in the backgroup. We changed out the power supply even though the voltages were ok. Noise still there. We moved most of the SS4 to the digital side which had no noise. I have another PBX just like this one in another office and have never experienced any issues. Other then the floppy and drive issues, we hardly have any problems.

Believe it or not, your back door power supply is failing. I think it's the 10v that goes out of tolerance, and causes the COV sets to go crazy!
