DX-120 7271C VM keeps crashing

I have a DX-120 installed about three months ago with the 7271C flash card that has crashed four times in the past three weeks.

When you dial the VM ports (157, 158, 159, and 160) or when dialing the hunt group 433, the VM doesn't answer...you only hear ring back.

The heart throb LED in the upper right corner of the board is still flashing and the flash card LED is still flickering. A tap on teh reset button restores service.

It happened two weeks ago, six days ago, three days ago and again today. After it crashed the third time, I replaced the VM unit with my spare one and swapped the flash cards to retain the prompts and messages, and set the corrected routing mailbox numbers.

The new unit just crashed today.

The DX-120 has a battery backup and they have a power outage for less than an hour at least every two weeks. I don;t know if there was an extended power outage the ran down the battery the first two times, but I do know that there were no power outages the last two times this week.

I don't think its a bad flash card, but what I'm going to do is reset the system and do an audio backup of the prompts (Audcity is a good audio editor) and stored messages (I don't want to back up the flash card per se as it might be corrupted). I have a adapter cable that plugs into the phones headset jack and my laptop.

If it stays up for at least two weeks, then it was a bad flash card. If it keeps dropping, I'll cold boot the system and reprogram it from a paper copy of the programming.

If THAT doesn't work, I'll replace the cabinet.

Any suggestions?

sounds like the VM is getting stuck in an endless loop rolling from port to port and tieing all the ports up. Next time it stops working, connect up with keylinkDX and see what the status of the VM is.
You may have a disconnect supervision problem on a line or a programming issue in a ucd group that sends the VM in to a loop when it is accessed.

That's what it sounds like to me too. I agree, I would be interested to see what the voicemail is actually DOING when it "locks up".

I went back this morning and the VM had fixed itself, so I didn't have a chance to look at the port status, although I know when I busy the ports by using four phones to call into the 4-port system I get a busy. When the VM is locked up, I only get a ring no answer.

I checked the system programming from a phone (I don't trust the PCDBA as it reports different settings than what I programmed by hand) and the settings were the same as the original setup and matched my paper copy. I did a cold boot and reprogrammed the system from scratch.

Now as for the PCDBA reporting the wrong information, the only two areas I've seen it incorrect were:
Ringing assignments - I programmed in by hand five extension - 101, 102, 103, 110, and 111; and those extension correctly rang; but the PCDBA showed 101, 102, 103, 108, and 111. I've played with the programming back and forth many times and have no idea why. When I use the PCDBA to set the ringing and upload it back to the switch, it works fine, but when I download what I just uploaded - 108 reappears.
Extension port swapping - that was a mess and I ended up doing it by hand.

As I recall, it was not the latest PCDBA version for the DX-120.

I'll see what tomorrow brings.

Another glitch in the PCDBA. I used the phone to reassign my attendant phone from port 101 to port 116 and it works just fine.

PCDBA shows port 101 swapped with 114, not 116. Oh well...

OK, looks like I'm going to have to replace the cabinet.

I did a cold boot of the system early this morning, did new programming from scratch (not a system backup) and the VM crashed a few hours later.

Since the original programming work for months, I don't thinks its a programming issue, and am using the same basic parameters on several other DX- VM systems

I loaded the K17 firmware update today and will see what happens.

I did have a chance to look at the system while in failure mode.

1) Keylink showed the ports idle.
2) Dialing each port separately returned a busy siganal.
3) Dialing the UCD group returned a ring-no answer (yes, I check to see if there were any other members in the VM UCD groups and there were only the three VM ports).
4) After I disconnected KeyLink, the VM rebooted itself. I heard it go through the boot-up beeping, which it usually doesn't do.

You have three voice mail ports??? Also I seem to remember that K17 didn't auto reboot the mail after a power restore. Sounds like multiple issues.

Sorry...I meant FOUR VM ports.

Anyway, the last four times this week, there were no power outages.

No go...the VM worked all weekend until noon on Monday. I'm going to replace the CPU board early tomorrow morning.

I'm still puzzled why you can get a busy when you dialed the individual ports, but a no answer when you dial the UCD group number, And I already checked, there are only four stations used fr the UCD members
