[Asterisk-Users] Extension 'hint' info please?

[Chris Coulthurst]

I have a Polycom 500 and would love one of the line-appearance keys to
show me if a certain person/people are on the phone upstairs.  This
'hint' priority seems to have little-to-no documentation.  So, if anyone
out there has a clue about this, here are a couple of questions:

Can you 'hint' Zap and IAX2 extensions?

Can you concatenate extensions together? 
(i.e. exten => 200,hint,SIP/101&SIP/202&Zap/4)

And the big one is.....


...how does this work on a Polycom 500?
