6.2 Placing Calls with Speed Dialing
You can use the Speed Dial keys, located on the right side of the phone, to quickly dial a speed
dial number. For configuring speed dials, see Section 4.2 on page 28.
 To make a call using speed dialing:
1. Press the required Speed Dial Memory key (M1-M10); the number or contact assigned to the
speed dial key is displayed.
2. Press the Speed Dial Memory key once again; the phone automatically dials the speed dial
contact’s number:
Notes:
• If you press a speed dial key that has not been assigned a phone number,
the phone displays a screen allowing you to assign a number to the specific
speed dial key.
• Your administrator can configure your phone to make a speed dial call by
pressing only once on the speed dial key (instead of twice).
6.3 Placing a Call On Hold
You can place a call on hold. This is typically used to answer a second incoming call or to make
another call.
 To place a call on hold:
1. During an established call, press the HOLD key; the call is put on hold and a dial tone is
heard.
2. To resume conversation, press the HOLD key again.
6.4 Answering a Second Call and Toggling Between Them
If you have an established call and you receive another incoming call, you can place the current
call on hold and then answer the second call. You can also toggle between these two calls by
placing the current call on hold and talking to the previously on-hold call.
The phone indicates a second incoming call similar to any other call (i.e., the LCD shows the
calling party ID and the LED flashes red), except that no ringing is sounded.
