Answering a second call (call waiting)
When you are on an active call, you can receive a second call. When the second call
comes in, the Call Waiting dialog appears, giving you the following options for
handling the second call:
• To place the current call on hold and answer the new call, use the 5-way navigation
control to choose Answer.
• To send the new call to voicemail, use the 5-way navigation control to choose
Ignore.
Making a three-way call
Talk to two people at the same time with three-way calling. Normal airtime rates apply
for each of the two calls.
1. Dial the first number.
2. While the first call is active, place a second call.
3. Use the 5-way navigation control to choose Conf. This joins the two calls in a
three-way call.
4. Use the navigation control to choose Hang Up All and end all the calls.
NOTE: You MUST hang up a three-way call before making any other calls.
