I have two customers with this issue and Mitel doesn't know or have any ideas about why. Their suggestions are the standard for the 3000 (reboot, default) which has all been done already. One of the customers even replaced their VM card with a bigger one in hopes of fixing the problem.

System:
Mitel 3000 with T1/PRI module

Occasionally, when someone is leaving a message on an extensions voice mail, it will transfer the person to the auto attendant. This happens whether the person is transferred from the attendant or calls the extension directly through the DID. It is not consistant and it does not happen after a certain period of time.

Both customers are with different carriers. Both customers are a good 1 hour drive from each other. Both are at 903 software.

Any help would be appreciated.

Check recall timers and COS

I've looked at the timers, but I have not made any adjustments yet. I cannot reproduce the problem myself.. so it makes adjusting timers a little difficult. But I will give it a shot and see what happens.

Is it possible voice mail card is maxed out, or that particular ext. is maxed out. You can set qty of messages per user I believe

Does this happen with only one or two exts?
Are they allocated VM boxes?
Check the programming for VM box allocated for ext. __

Voicemail is not maxed out. I've checked several older databases and they never have more than 6 total messages for the 30+ extensions that they have. And of those extensions that did have messages, there were only 1 or 2 per box.

It does not seem to follow a specific extension. And yes, they do have boxes associated with their extension. The callers are midway through leaving a message when they get booted to the attendant.

I was able to speak to Mitel support yesterday. He suggested that it could be higher octave (female) voices that are triggering the VM to think it heard a 0. I contacted both customers and one thinks that it has been women having issues. Both are going to keep track and report back.
