1. You can buy a bluetooth for your cell phone, if that is the phone you prefer using.OK, I have a headset that I bought several years ago but it plugs into my computer..(not USB) Can't use it with my cell phone.. My home phone is a Verizon Home Phone..
2. As others have suggested, buy a headset compatible with your home phone, if it does not have speaker features.
3. If you prefer VOIP, buy a compatible headset.
