PLEASE HELP!!! My phones programmable keys are not allowing me to set them up as DSS keys. Out of the 20 keys, 10 of them are programmed as BIN keys or dialing an outside line which are meant for speed dials. As I don't use speed dials but I do use the Direct Station Select keys, I only have 3 that can be prgrammed to dial an extension. PLEASE help me to program my phone to have more DSS keys and not keys that go to an outside line. THANKS!
