I have Aastra 6730i; comes with a power adaptor, one Ethernet port, and no PoE. It's a nice phone, great speakerphone, but their firmware is as horrible as it gets. Anyone on your lan can see your SIP password by logging into the phone with the default admin/22222 password (no way to change the default password!), sometimes the Line buttons magically swap themselves out (it once got into a state that a ring that's supposed to appear on Line 3 would always appear on Line 1 instead; and what was supposed to appear on Line 1 (then Line 2 if Line 1 is busy), would always appear on Line 2 instead (since, apparently, Line 3 somehow moved into being Line 1); it was happening for several weeks like this, until I've finally rebooted the phone, which brought Line 3 indicator back to Line 3, and Line1/2 back to Line1/2). I apparently have provided some partial review of this phone here: »Re: Aastra logging
In summary, excellent visual design and build, great rubber buttons and loud speakerphone, ability to use several independent SIP accounts and HD voice, but the software is full of bugs.
