Query: Good sound, but not very convenient

The phone works great, love the conference feature. The biggest downside is that you can only use one phone from the set at a time. So if you have the base unit phone and a couple extra handsets, only one can be in use. If you answer one of the phones and it is for another person, he/she HAS to use the phone you answered. The other phones will not pick up the call. So you have to walk the phone to them even though they might be sitting right next to another handset.
