Ihave an OS 100 with 4 WIP phones over two WAPs that give complete coverage to my clients building. The problem that they've been having is when a call comes in none of the buttons work except for the disconnect button. It doesn't happen all of the time, however it happens frequently enough to bother them. I've come out and check the signal strength of the WAPs(looks good), I've checked to see if they have locked the buttons(they have not), and I've checked to make sure the phones are registered with the system(they are).

It only happens on incomming calls. Does anyone have any insight to this situation?

Thanks,

Rob
