What are four good telephone habits?

There are a few simple rules:

• Identify yourself. As much as you think the caller should know you, he might not.
• Check the number before calling. If you get a wrong number apologize.
• Don't hang u after one or two rings.
• If you leave a message speak clearly and don't rush through your name or the return number
• Speak clearly, don't whisper or yell, don't eat while talking
• Keep it short if it is a business call
• Have all the information you need readily to hand
