There are 12 vm port licenses.
When they dial 2500 they get the message in the heading.
They are getting bombarded with calls. 400 in a 6 hours period.
First thought is the VM ports are busy, but....
When they dial in from the outside and hit the auto attendant, they can * out to get their messages.
If you can dial in and get the auto attendant, the ports have to be free.
What might I be missing here?
