Siemens Gigaset S450 IP Dect SIP Twin

Had this phone for 9 months now. Tweaked things and discovered things that aren't in the manual. You can set 6 voip operators, if you have several incoming voip numbers you could assign them for use by different users so that when the phone rings is states who the call is for. Have managed to figure out how to dial via different voip providers without having to go to the PC first, set up the providers from the web config then append each number with #1 for provider 1, #2 for provider 2 etc etc, or simply set up dial plans via voxalot.com. There's simply no other phone out there that provides you with the options that the S450IP does, you can even combine it with the M34 USB adapter and use it for sykpe as well.
