If you don’t have much experience of making phone calls in English, making a business call can be a worrying experience. Most business people, unless they feel very confident, prepare for an important phone call in a foreign language by making notes in advance. And during the call they make notes while they’re talking to help them to remember what was said. Although it’s quick and convenient to phone someone to give them information or to ask questions, the disadvantage is that there is nothing in writing to help you to remember what was said. It’s essential to make notes and often when an agreement is reached on the phone, one of the speakers will send a fax or e-mail to confirm the main points that were made. Because it’s so easy to be misunderstood when talking on the phone, it’s a good idea to repeat any important information (especially numbers and names) back to the other person to make sure you’ve got it right. Always make sure you know the name of the person you’re talking to. If necessary, ask them to spell it out to you, so that you can make sure you’ve got it right----and try to use their name during the call. And make sure that they know your name too.1.
