70 Section 2A: Making and Answering Calls
Nextel Group Walkie-Talkie Calls
Your phone does not display an incoming call notification for
Group Walkie-Talkie calls. It does display the calls in the Call
History.
Nextel Direct Talk
Because Code calls do not take place on the network, your
phone does not track them. However, you do receive
notification of Private calls and they are listed in Call History.
