It's called call waiting and while your on the phone you will hear a beeo, then you hit the flash button or push and release the receiver and it will switch you to the other caller, then you can go back by doing the same thing....

Answer 6

there should be a little beep when you hear that and your already on the phone with someone else you tell the person that your already talking to "bye" or "hold on a sec someone's calling me" then you press "flash" or "line 2"
