I've had really good luck the last 3 months working from home using the ATT TL96271 cordless phone system with Bluetooth Link (links cordless phone to cell-phone) along with the TL7600 DECT 6.0 headset. The range of the TL7600 is much greater than any Bluetooth headset I've had, and being able to answer and dial from my cell on any handset in the house (including speaker phone on the base) is very handy... my cell phone now sits on the charging dock in my home office or next to my bed unless I'm out of the house. The TL96271 can connect simultaneously to 2 cell phones and 1 land line (though I only use it with the 1 cell phone). My only complaint is not being able to dial from the TL7600 headset, and the somewhat cumbersome process of dialing from the handset/base, waiting for the call to connect, turning on the headset, and then turning off the handset.
