I have a client with a Legend 7.0 and VM MLM007. Extension 27 is one of the operators and is designated as the "call answer service operator".
Between 10 and 20 times a day her ext will ring one ring and it will be from ext 54 or 55 which are the first two ports of the VM. If she grabs it, it's dead.
I have done quite a bit of troubleshooting on this but would rather start from scratch with some fresh ideas. Maybe I am missing something simple.

So, What would cause this type of problem in the first place?

Does the client have a T1 circuit connected to the Legend and, if so, are the ports on the T1 configured for loop start signaling?

They have analog lines and the system is in key mode.
This operator has lines 801-803.

Check to make sure positive disconnect is set to "Yes".

Dexman meant LS-Disconnect in Lines and Trunks fetures.

Under Aux Equip > Vms/AA I would play with TransferRtn, and make it longer than default.

Reliable disconnect is set to Yes and TransferRtn is set to 9.

Shooting from the hip here as I'm not very experianced with the Legand, But make sure you don't have voice mail boxes asigned to extensions 54 & 55 . Experianced same problem on Partner and found that by having a voice mail box asigned to a voice mail port, If someone mistakingly leaves a message in the box the notification is a 90v ring burst which the voice mail sees as an incoming call, transfers to operator and then hangs up. Hope this helps.

Well, if you are talking about VMS Transfer Return is 9, and RELIABLE Disconnect is YES, then you are probably NOT getting a reliable disconnect from the CO.

This is easy to determine.

STEP 1 - Place a call to the system from your Cell Phone. - Answer it on the SYSTEM, and put it on hold.

STEP 2 - Hang Up your Cell Phone.

If THE CALL ON HOLD DROPS, then YOU ARE GETTING CO Disconnect.

However, if it DOES NOT, then what you want to do is UNPLUG THE LINE the call came in on from the system.

IF THE CALL NOW DROPS, you have PROVEN that you ARE NOT GETTING a disconnect signal from the CO.

I tested for CO Disconnect and it disconnected on all lines just as expected. But, I was able to duplicate the problem.

When I call and the AA picks up I press "0" to get to the operator. On my end it rings a three times and goes into her VM box. On her phone it rings one time and that's it. She cannot pick up on the call.
I set her VM coverage to 5 rings and I thought that fixed it, but she just emailed me and said it is still doing it.
