3. Wait until your call is answered.

2. Subscriber Trunk Dialling (STD)

You may use a telephone operated by a system known as STD (Subscriber Trunk Dialling).

1. STD is quicker and cheaper, so dial as many of your calls as you can.

2. Maintain in your Personal Telephone Directory an up-to-date list of dialling codes and/or number of people you are likely to call. This will save you time in the future.

3. When you dial, don’t pause too long between digits.

4. If the number you want is engaged, wait a few minutes before dialling again.

5. Ask for the extension number on calls to a private exchange, this will save you time. If the extension you want is engaged it will usually pay, on an STD call, to clear and try again later.

6. If you hear a recorded announcement telling you that the trunk lines are engaged, replace the receiver and try again later.

7. Answer your telephone promptly, giving your name or the name of the office or telephone number. This saves the time and helps the caller.

3. International Subscriber Dialling (ISD)

You can dial for yourself calls to most places in Europe and North America.

1. First dial the code of the country or the code for the place concerned and then the subscriber’s number.

2. If you wish to know the code for a place which is not shown in the Telephone Directory, ask the exchange operator.

3. When dialling to Europe or North America don’t pause more than two or three seconds between digits, especially the last few digits. The call may fail if you do. It helps to write down the whole code and number before you dial. You will often hear nothing for a half a minute or a little longer after dialling.

4. Do not replace the receiver before you have given the equipment time to connect the call.
