You have a flashing Voice Mail Light but you
have no messages.
There can be several reasons for your phone to have a flashing message waiting lamp.
Usually it's flashing because you have a voice mail message waiting for you.
But not always.
The Mitel product line has existed for decades. It actually pre-dates the
general availability of voice mail itself. (Can you remember those days?) In the good 'ol
days, if you wanted to have someone in your office call you, you would call them and while their phone was
ringing or while you were listening to a busy tone, you would press the message waiting button and the
message waiting light of the person you were calling would light. This would alert the person that
someone wanted a call back. They would then pickup their handset and press the message waiting button
and it would call the person who light the light. Once the other person answered the light would go
This isn't generally the way we use this button any longer. Now when we see the
light lit we expect to have a voice mail message waiting for us.
Here's how to solve this problem and get your MWI
light to go out.
If you have a display phone, hit your message
waiting button. Then push the "Read Messages" button then the "Call Back" button. This will show
you who lit the light. Press the call button and it will ring their phone. Once the person
answers the light will go out. You may have the option to, rather than hitting the "Call" button, to
hit the "Erase" button. This will turn out the light without calling the other person.
There are some other reasons your light may be on
without you having voice mail messages.
1- You have buttons on your phone that have a
voice mail box.
Resolution: Add a specific "Message Waiting" Button on your phone for
those lines. Then you'll know you have a VM for those numbers and not your phone.
2 - You have keys on your phone that belong to
a hunt group of keys. This hunt group has a voice mail box. Your phone just happens to be the
phone with the 1st appearance of the first member of the hunt group.
Resolution: This is a much more involved programming effort.
There are several steps that the Mitel tech will have to do.
(A) Delete the hunt group
(B) Renumber the 1st member of the original hunt group on all phones
to be the number of the original hunt group.
(C) Create another hunt group with a new non-DID number.
Put all members in this new hunt group starting with the member that was renumbered.
(D) Create a new call rerouting 1st alternative index to forward all
calls to the new hunt group on a busy condition. Set all the No Answer condition fields to say "Last"
(E) In the Call Rerouting Attributes form find the original number
and assign in the 1st alternative field the new 1st alternative index number and in the 2nd alternative put
the index number from your "Call Rerouting Second Alternative" form (usually '2').
(F) Program a Message Waiting Indicator key on your phone for the
original number (not the new hunt group number).
There are some other things that may cause your
MWI light to be lit but in general the ones mentioned above are the most likely suspects.
One thing you can also try if the above doesn't
work for you is to enter the message waiting MWI On Code along with your own extension number and then
the MWI Off code plus your own extension number. This sometimes works where all else fails.

Advanced Tips for the Techies
With the embedded voice mail, you can download a log file that
may give you a clue as to how the light was lit if it was light by the embedded vm.
FTP into your 3300 using
FileZilla. Change to directory
/vmail/c/voxdrv. Download files diag.dat and diag.sav.
Open diag.dat of the files with Notepad and look for the 3a.m.
Look for your Message Waiting "on" code and make a note of the
mailboxes that are having their MWI lights activated.
Next log into your PBX and go to Maintenance Commands.
Enter "locate <num>" for each of the mailboxes noted above.
What you're looking for is either a hunt group that has some
association with the complaining phone or a system speed dial number that points to the phone with the
