I have only put in a couple of these. Just got an email from a customer saying that the ext #102 button (DSS one touch) on all of the phones was fast blinking.

I assumed 102 had inadvertently been put into DND so sent him the info to cancel DND. That did not work- and they are able to call ext #102 from the other phones.

Is there any other feature that would cause that to happen? He said a new employee was mashing some keys on the phone when this came up....

Any suggestions would be appreciated - 100 mile drive if I have to go there myself.....
