Why should Panasonic or any other manufacturer provide two way transmission on a page port? Of the systems I have sold, you have very few that don't just put an amplifier on the page port and it's one way.

Now in the old Comdial days, you could make any voice port or trunk port page so it was 2-way, but it seems to me that Partner, Panasonic, Vodavi, and the like were one way paging only, ans some of them wouldn't even let you send dtmf to a Valcom zone page on the page port.
