Hello ... Hello ... hello ....
I got a USB headset and a phone-like device for use with Skype. I also paid the tiny annual fee to have my own phone number. I called that number with Skype, and, of course, it looked like I was receiving a phone call while I was trying to place a phone call. Naturally, I had to conference the two together to see what would happen. At first the soft echo was funny. Then it got really loud and was less funny. Now you know.
