Wait. You have a speaker to monitor any call on an outside line but if you wish to speak you must use the handset, no microphone, correct. But, on an intercom call, it can be hands free one way. It uses the speaker as a microphone. If a party intercoms you using the handset, you can respond hands free, if they leave the handset down, your phone will ring and you need to pick up to talk. That's how I remember it, but I have been wrong before. One time when I thought I was wrong and it turned out, I wasn't. wink
