78 / Making calls

Using Pre-dial

Pre-dial allows you to enter a telephone number, check it, then change it before actually making the call. The call is not dialed until you select a line or line pool, or pick up the handset. You can pre-dial both external and internal numbers. You must, however, select the correct type of line (external or internal) for the type of number you have entered.

If your telephone starts ringing while you are pre-dialing a number, you can stop the ringing by turning on Do Not Disturb ( °fi). This does not affect numbers you are entering￿.

You cannot pre-dial a telephone number if all the lines on your telephone are busy.

When the internal number you have called is busy

If you get a busy signal or a Do Not Disturb message when you￿callfl· someone in your office, you can interrupt them. Use this feature for urgent calls only.

Priority calls cannot be made to Hunt Group DNs. For more information about Hunt Groups, see ‘‘Programming Hunt Groups’’ on page 171.
