Receive a PTT call
A short tone notifies you of an incoming channel and one-to-one call.
When receiving a channel call, the channel name and the nickname of
the caller are displayed. When receiving a one-to-one call from a person
whose information you have saved in Contacts, the saved name is
displayed if identified; otherwise, only the nickname of the caller is
displayed.
You can either accept or reject an incoming one-to-one call if you have
set the phone to first notify you of the one-to-one calls.
If you press and hold the volume up (PTT) key to try to respond to a
channel while another member is talking, you hear a queuing tone, and
Queuing is displayed as long as you press the volume up (PTT) key. Press
and hold the volume up (PTT) key, and wait for the other person to
finish; then you can talk.
