Since you're using them with asterisk (this is the asterisk-users list 
after-all :), why not implement it in asterisk? Asterisk even has the 
voice prompts already for it too, so someone's obviously though about it 
in the past...

And this is exactly what I do in my systems, and the beauty is that it's 
completely phone independant. You could have DECT phones, desk phones, WiFi 
phones, soft phones, etc. all sharing the same phone-book.

Sure, it's not as neat as an in-phone solution (you can't easilly scroll 
through the list on the phone), but it's universal over all phone types.

I implement a per-extension phone book, and a system phone book which 
everyone has. And with a web interface, you can associate a name to the 
number, then incoming caller-id works too, as long as the phone has a good 
display.

Heres a working example from some old code I wrote - which I'm sure I got 
off a web page (or the book) once upon a time in the past. (The list 
commands here won't work with Siemens SIP/DECT phones as they won't let 
you dial a trailling star, it's a # in the latest incarnation) This is 
only 10 numbers per phone, but it's easy to change for more (eg. *000 
through *099 for personal ones, or *100 through *199 for system ones - 
left as an excercise to the reader ;-)
