Nifty idea, mostly pushed by [Cisco]. The idea is that instead of wiring your buildings with [Ethernet] and phone, you just wire them with [Ethernet] and you use [VoiceOverIP]. So you have very nifty phones that plug into Ethernet and use [DHCP], [H.323] etc. Very nifty.

+
+!!!Cisco IP Phone 7912 Series
+
+Sorry for messing up this page - busy :)
+
+First Looks:
+
+!Pros
+* Looks cool!
+
+* Appears to be able to access a basic [HTML] webpage for phone directory lists/etc that is served on the local [LAN]
+
+* Appears to support PoE.
+
+* Has extra Ethernet port on the back - this means you plug your Ethernet cable into the phone, then plug the ~2m Ethernet cable supplied eith the phone into the phone, then into your computer. This means only one [UTP] (Ethernet) cable is required.
+
+!Cons
+*The [Ethernet] cord(s) attached at the back interfere with the phone sitting down on the desk, e.g. the phone has a bracket that sits the phone at a 45 degree angle to desk - Ethernet plugs into the back between the desk and bottom of this bracket - would be better to have no rubber-boot/plug-doo-dad-wotsit on the [UTP] plug... on second thoughts, I think Cisco' book mentioned that you should use no jackets on the [UTP] plugs...
+
+
+*Does not come with SIP image pre-loaded (only Cisco' Skinny? image)... you need to get a Cisco SMARTNet support contract, then when you have that, create an account on their website, then upgrade your Cisco account with the SMARTNet details, which let you access the SIP images for the phone!
+
+*Requires a 48V DC @ 200mA power supply - somewhat hard to come by... cheaply.
+
+*Once the SIP image was loaded, and (very) basic setup sorted, phone had a ~60ms ping time to it when not even being used...
