Phones for Home Office
[Dani],
I already purchased the Plantronics headset and AT&T speakerphone. I got the AT&T speakerphone also, because the phone I had been using before was a Radio Shack headset phone. It was a full-fledged phone but had very few of the features I wanted – no extra memories, no muting, and no speakerphone option. So, I thought it best to replace the whole phone.
At any rate, on the cordless phone, I’m pretty happy with the new one I have now and so won’t be needing the cordless one. However, if I determine that at some point, a cordless phone would be helpful, I may pay for this one myself. I’ll keep your cordless option in mind. 
Later.
