CONSIDERATIONS A headset cannot be used with a 5-button voice terminal.

The cord on the headset is plugged into the headset adapter, and the voice terminal and the adapter are connected by way of a modular cord which comes with the adapter. The headset adapter plugs into the jack labeled "Other." Since the 10-button HFAI voice terminal does not have an "Other" jack, you cannot use a headset with this type of voice terminal.
