We have a set that when you go off hook for intercom the set beeps 3 times then the intercom dial tone. On all of the phones that has a button programmed as a DSS key for this set it is flashing red. Have gone into the set, looked at the DND and it is off. Tried the MW cancel codes. The set looks and works normal. You can call the set and transfer calls, works correctly. Tried rebooting the system and the DSS key still flashes on all of the sets.
Are we missing something other then MW and DND that would make a DSS key flash?
