More VoIP hardware: A Siemens Gigaset C450 IP. Big downside: I needed internet explorer to configure it! It runs a small webserver for configuration, but all javascript was broken in firefox/mozilla. But after the usual swearing at Windows and IE I was able to make it talk to asterisk, with a bit of help from the hints at voip-info: Siemens Gigaset C450IP. It is a nice SIP dect base (with analogue landline support) + handset. A real shame about the IE bit.. it does run Linux inside!
