Avaya J179
The phones in the main office are the new Avaya J179, model. These offer an almost identical way of operation, however they do provide additional line keys on either side of the display.
Please see the reference Sheet below for detailed information, on the functionality of the phones.
When dialling an external number you no longer need to dial 9 first. Just dial the number as you usually would outside of school or on your mobile and within a few seconds the number you have inputted will be dialled.
