Nortel Networks Modular ICS 4.0 When the internal number you have called is busy, Using Pre-dial

58 / Making calls

Using Automatic dial

Automatic dial allows you to dial a number without selecting a line. Your prime line is selected as soon as you start dialing a number.

Automatic dial does not work if your telephone has no prime line or if your prime line is in use.

Telephones connected to an analog terminal adapter (ATA) cannot use Automatic dial.

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 receiver. 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.

Tip - If your telephone starts ringing while you are pre-dialing a number, you can stop the ringing by turning on Do Not Disturb ( ƒ°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.
