:confused:
I have a customer with a NAM 3.0. The other day 18 mailboxes lost OPN programming. All were programmed as a phone and the pager number, i.e.,
phone: 9XXXXXXXPPXXXXXXX. This has worked for years without an issue. The VM is constantly paging. Now, at random, it is happening to mailboxes with unique passwords. Has anyone seen this before?

Check you lines! You're using line group access and the NAM isn't smart enough to know its hitting a dead line!!

What is happening is the OPN programming is gone. If you go into the MB and check message notification programming, all entries are gone. This only happens to those entries that are setup as a phone. I am wondering if it is possible for the pager company to be sending a DTMF tone that the NAM is interpreting as a 2.

The paging company cannot change what you send them. If passwords have not changed and an admin password is in place and there is no remote access into this NAM you need to back it up and do some disk maintenance. You have some bad sectors and the drive may be failing!

I am not suggesting that the paging company is changing what we are sending. However, if they send a DTMF tone that is interpreted as a 2 by the NAM then it would remove the number. The NAM does not know if the device that you are connecting to is a cell phone or a pager. When they are connected, even for a brief moment, a digit 2 will remove the number. I am not sure if it is possible for the paging company to be doing this. The problem is intermittent with different mailboxes. This only happens when the destination is set up as a phone (which allows for digit 2 to be pressed which removes the number). It has not happened when the destination is set up as a pager. We will be changing them all to pager.
