USING THE IP250D

4 Using the IP250D

This section describes how to use the IP250D. The references and actions associated to the "LINE 1", "LINE 2" keys and LEDs apply to the SIP version of the IP250D only. The "LINE 1" and "LINE 2" keys and LEDs are inactive on the MGCP version.

4.1 TELEPHONE IDLE

The IP250D is in an idle state when the handset is on-hook, the headset and speaker are off, and the user is not attempting to use or configure the phone in any way. The IP250D displays the date and time when the telephone is in an idle state. The date and time may be displayed in a MM-DD-YY, MM-DD, DD-MM-YY, or DD-MM format for the date and a 24-hour or 12-hour format for the time. The phone also displays its extension number or telephone number.

4.2 INCOMING CALL NOTIFICATION

The phone provides notification of an incoming telephone call in three ways:

1)The phone rings using a tone chosen by the user. Different ring tones may be chosen for internal and external calls.

2)During an incoming call, the IP250D flashes the LED for line 1, if no lines are active. If line 1 is active but line 2 is not, the phone flashes the LED for line 2, and if line 2 is active but Line 1 is not, the phone flashes the LED for line 1.

3)The IP250D displays any caller information (if available) on its display.

4.3RECEIVING A CALL

The IP250D allows the user to receive a call and establish a virtual audio connection with the other party through the handset, speakerphone, or headset:

HANDSET – From the idle state, the user may receive a call by lifting the handset, thereby placing the IP250D off-hook. If the user is already conducting a conversation with another party, the call may be answered using the handset by placing the initial party on hold and pressing the LINE 1 or LINE 2 key corresponding to the new call. If the phone is idle but the handset is already off-hook when a call arrives, the user can receive the call by hanging up the handset and lifting it again, or by pressing the LINE 1 or LINE 2 key corresponding to the new call. The user will be able to identify the proper line key to press because the LED above that key will be flashing.
