This is not entirely a hot deal, but I think may be useful info.....
IBM headset phone
A less advertised feature of this phone is that it has inputs and output which you can connect to your sound card and you have a cordless headset for your computer.
This is NOT the best price for the phone , I paid $99 for it at Sam's Club.
I looked for cordless headset for a LOT of time but was unable to find anything - but now I dont have to be stuck in front of the computer when I am talking via dialpad
If you have a better way of accomplishing the same , please share
