atcomsystems.ca/forum Forums TDM Business Telephone Systems Comdial Telephones & Systems DX-120 7271C VM keeps crashing

To recap, the VM had been running fine for about three months and then suddenly started having the problem. And the problem got progressively worse from one reboot a week until the third week and it was locking up daily.

Comdial had me turn of the automatic 3 AM restart and made sure all my dial codes pointed to valid prompts. The VM was stable for the following three weeks. Unfortunately I replaced the CPU at the same so I didn't know what fixed the problem. However it locked up yesterday. I'll wait a few days to see if it starts getting worse again.

Lines are T1, so not likely a bad line issue, per se. The power does go out for a second at least once a week, but the system is on a UPS.

I tried both ringing to four specific phones and then a UCD group and made to difference.

UPDATE - -

It was running great for about two months after I upgraded to F17, and turned off the 3 AM reboot.

BUT...It crashed four weeks ago, last week, and again this week - TWICE on the same day. Thats four times this month.

I'll upgrade to F19, but I still suspect a motherboard / power supply issue as I've already replaced the flash card VM and CPU board.

F19 info says it does fix the problem of VM not coming up after a power outtage, but I have this system on a battery backup and customer says there has not been any significant power outtage (it does go out for a few minutes almost every week though and never on the days that the VM has been crashing) and another customer right next door never has a problem with an identical system.

A Vertical rep told me "I'd reboot the entire system instead of rebooting the VM only when this happens."

Don't ya love that!
I always tell them that a reboot may mask the symptom, but it doesn't fix what ever is causing the trouble.

Actually what eh said in full quote was, "I didn't say this. I'd reboot the entire system instead of rebooting the VM only when this happens."

In regards to VM locking up,

I had a DX120 with 7271C VM doing the same thing

After 2-3 weeks of reseting system I made some changes in the phone system UCD groups for routing calls from voicemail.

Make sure if the voicemail routes to a UCD group, that the (reroute destination) isnt an extension that is located in the that UCDs (members list).

That fixed that problem.
Now the problem with the time being incorrect on voicemail has started (4 months after) I think I will update to L19 software and see if this takes care of the probem

Thanks

I recently had this trouble on a DX80 system 18 mths old, first it had a bad flash card which I replaced. Then it started shutting off every day, a reset would bring it back but it would shutdown again in a day or less. I replaced the board & flash and had the same trouble. Yesterday I did a cold start and reloaded the database from a copy I had from several months ago. So far it's still running, it's been 24 hrs.

Mine is down again this morning, appears the new VM board has a corrupted flash card, I'm preparing another new one for them now. I'll follow up tomorrow.

Don't ya just love it. You make maybe 1,500 profit on the sale and then piss it all away on go backs.
Have you tried grounding the spare pairs? JK. That was always my favorite response from Comdial tech support in the 80's.

Bad flash card. check disc found numerous problems, running the fix appears to work but once the system use hit the bad sectors the allocation errors returned. Disc doctor did not work and wiping it clean and reloading had exactly the same problems. I replaced it today after testing it here for hours and bombing it with calls. Seems ok now, we will see. You can't get an rma just for the flash card, you have to return the whole thing, so that's what I'm doing. Pity the dealer that doesn't keep stock of their products.

I upgraded to last week and the system is still going down every few days. The only thing I haven't replaced yet is the cabinet and the flash card.

I can record all the prompts and messages on to a CD and pass out individual CDs for about ten users.
