Tom Keating has a post about TMC's (Internet Telephony) IT Expo last week. A couple of brands were everywhere. Unlike Polycom, one brand had just 2 spots: Aastra. Aastra sells IP phones, including a cordless DECT handset (480i-CT). Dell distributes Aastra with its Fonality boxes. (other source). Aastra has a developer's portal for XML. You can program these phones for lots of stuff including weather, CNN, and Caller ID screen pops from CRM.
