FWIW, the cordless handsets on the Aastra 480i CT work well. I've waled about while on a call, to a distahce of approx 300 feet before the call quality started to suffer. The phone supports up to 8 (I think) handsets, treating each as a separate extension. It can page between handsets without involving Asterisk. It supports up to 9 line appearances, which means that all the cordless and the base units can be on a call at one time.
The only thing that I hated about the Engenius phones was the fact that they didn't support a plain 2.5mm connector for a headset. The 480i CT is pretty awesome.
