We put in a 7100 with 4.04a software, ox16 DLi in middle slot, two 4x0 dial tones in right slot. 211 and 213 would lose their mailboxes, No in 741.
You could call in and reset 741 but the same problem would occur again at random days/times.
Upgraded 4.04a to 4.14 and put in all data by hand again. Next morning, 211 and 213 mailbox set to no in 741.
Replaced the MP10 card. A couple days later the same problem, 211 and 213 would lose their mailboxes, No in 741.
Additional weird was that on 211 and 213 we lost the third row of button programming on those two phones. In 723 all the buttons from 1 to 10, 16 to 28 are identical. The row of 11 to 15 were all set to DS and in 722 we set the individual DSS keys for each phone.
On 211 and 213, every time the VM box disappears, so do the DS numbers. On 11 through 15 you see DS but not the numbers we programmed.
I have assumed that all control is by software and the MP10 card. Is it possible that the 16DLi card or the frame could be doing this. It doesn't seem rational that they could do this weirdness.
Any and all help would be appreciated. We have made almost a dozen free service calls on this and while the customer has been polite, they are tired of this. So are we.
