Just a quick note - some people ask us whether they can use phone functions from their wireless headset (like a Plantronics CS10, CS50 or GN Netcom 9120).
The short answer? No.
If you're using a cordless headset, you can answer remotely (using an optional Handset Lifter like the Plantronics HL10 or GN 1000), but that's about it. You can't transfer calls to another extension or make a call because those are functions of the telephone, not of the headset.
If you're in a home office situation and only have a single line, you might consider getting a complete headset phone system like the Plantronics CT12, CT11 or CT10 . The CT12 provides call display and 2.4 GHz DSS (Digital Spread Spectrum) technology. The CT11 is a 2.4 GHz model and the CT10 is a 900 MHz model.
