Just a little footnote, it is also considered proper etiquette here in the US that the person who placed the call is the one who should end it. This can be a real problem if you have friends who think nothing of calling and wanting to talk for HOURS!! I actually have a friend who will talk on and on and at some point I will try to indicate that I need to move on and finally she told me "If ever you need to go, just hang up on me like my other friends do." I cannot bring myself to do this, so in particularly long conversations it might be 30 minutes of hinting that I need to go, before she will say good-bye. This is where caller-ID comes in handy, if I do not have time available to talk for hours, I call her back and then I can end the call when I need to!
