We have a KX-TD816 system and I have a KX-T7431 phone. We have no operator so whoever picks up transfers. No one can transfer to me anymore. One other thing all the phones the FWD/DND button blink slowly. Mine doesn't anymore and no matter what I try it won't blink including changing the phone out has been tried.

Apologies. I guess I was supposed to come to your place and do the work for you.

The only reward we get from the free forum in FixYa is your rating. I went to TD training in 1994. Even though the system was discontinued about 7 years ago, I still have several systems in my customer base. In an idle phone, every time you press the FWD/DND button in a TD series box, the forward status changes. 7100 on the intercom clears everything, the 710x codes set it up. Once FWD/DND is set, the button becomes a toggle. That is absolute.
The display guides you through the functions by telling you on the display and visually displaying under the button what status it is in. When someone calls you, their display will also show a status. You may have turned on messaging (750x codes) but the FWD/DND button still controls the phone.

So that we don't have to ask for clarification and go back and forth, it's easier to answer your question and point out the possibilities. "they can't transfer to me". Well, is your phone in DND or forwarded? Did they lose thier buttons? I don't know and I'm not coming there to find out. Help yourself. Answer the questions asked if what is suggested doesn't work instead of giving the solution a bad rating. This is not rocket science. It's a phone system with finite solutions.
