The way you describe what you want, there is no need for multiple
buttons on your phones, just callerid is good enought since it gives
the best visual for the users. In fact long before callerid was
available to the comsumer markets, companies used this when ppl called
different DIDs or groups from menus.
All you would do would be to change the caller id and then have the
call go thru the regular dialplan of ringing your extensions. You only
need the new extensions if you want a different voicemail (which can
also be accomplished in other ways, but some times this is the
easiest).
