Although I think it's pointless just stating a phone type - this doesn't 
actually answer the posters questions..

This I don't know about - Just how do you monitor a Zap line from a VoIP 
phone, and arrange it so that pushing a button on the phone connects you 
to that line...

Personally, I'd re-educate the users - they now have a PBX and not a 
Key-Line system.  Old habits die hard though...

See the Page() application.

Page again - the "trick" is to get the phone to (a) auto-answer when a 
magic command ise sent to it (or if it's a muli-account phone assange one 
account to auto-answer in speaker phone mode), and (b) hangup the call 
when the remote end hangs up.

The Page() function has 2 modes - one speaker, 1 or many listeners (one 
way talking) and complete full-duplex (2-way intercom mode, but you really 
only want to do this between 2 phones!)

>> Any suggestion on Phone and how to implement?

I know that Grandstreams and Snoms support the Page() function - presumbly 
the Polycoms and most others do too, but I'd really think about the 
re-education step to move from a Key-Line to PBX system...
