Depends on what you'd want precisely. Here's a (higly undocumented) example 
(I'm working on more). I used KPJ's examples on www.junghanns.net to start 
with (thanks!) and have a few more tricks up the sleeve that will take more 
time to evolve...

Brief instructions: Make sure the phone has a callerid that matches the 
extension number (makes sense, but might not always be true). Then make sure 
the phone can dial the entries in [apps].

If you use this setup a phone can dial *21*<number> for immediate redirect or 
*61*<number> for delayed redirect, and #21# or #61# to cancel the setting.
