Let's make it clear....
You will need 1 station port to connect 1 C6. To try Curly's work-around you would need 2 others. If you don't have the extra 2 then you'll have to settle for CLID going directly to only ONE extension. The others would have to hit a button with F811 programmed to it if they really want CLID before they answer unless the call was transferred from the extension that has it automatically.

The only other way for everyone to get CLID would be to install a Flash 2 voicemail, set to absorb the 1st 2 rings. When the caller selects what extension they want, then the CLID will be transferred to that extension...

I believe Nortel's original thinking on this was due to privacy concerns. Example: Say "Mary" was receiving a call from her doctor, who was a local "well known specialist". Mary possibly wouldn't want her colleagues to know what her problem was.

Scientists say that the universe is made up of Protons, Neutron & Electrons. They forgot "Morons".
