KomplettPBX has put together a very nice userguide for Asterisk phones using the Aastra 9133i phone. Is anyone aware of similar works for other handsets such as the GXP-2000 or other Aastra phones? To see what I'm talking about, go to the FAQs section of http://komplettpbx.com Komplett is to be commended they've done a nice job.
