asterisk users - Oct 2003 - multiple SIP users on one phone?

Interesting problem:

An organization has departments.
Each department has a single phone.
Each department has multiple people.
Each person within the organization has a direct dial incoming number.

It's easy to set * up so that multiple DDIs get mapped to the same 
extension.

What I'm wondering is if there's any way, with reasonably priced 
hardware, to notify the person who's about to pick up the phone who the 
call is for. Maybe change the caller ID field or something?

In an ideal world, the hardware would have two lines, one with caller 
ID, one with the name of the person they're trying to call. 
Additionally, a person should be able to field a call, decide they can't 
deal with it, and push a button that redirects the caller to the 
appropriate person's voicemail (based on the incoming DNID).

Is any of this possible? Phone cost per handset should be as low as 
possible, as per usual. :)

I have no experience of SIP hardphones, so don't know how much/what 
information about the call they're capable of displaying.

Regards,

The Cisco 7960 supports six lines, meaning six DID's, and inbound 
calls will flash the appropriate line icon on the LCD screen. 
Similarly, if the correct line appearance button is pressed before 
dialing, the outbound SIP call will appear to originate from that 
particular line.  Each line also has it's own MWI indicator on the 
screen in the form of a flashing envelope.  Price is ~$300 these days 
for used 7960 phones, and then you'd need to contact Cisco if the 
phones did not already have the SIP image on them.
