Application Is Not Visible during an Incoming Call
Check the Background Mode setting to ensure it is not enabled. For more details, see the Changing
the Background Mode Setting on page 151
section.
22.6
Call Failures
A PTT call may not be completed for several reasons:
• The person you are calling has an “Offline” or “Do Not Disturb” status. The PTT application does not
allow you to make a call to someone with either status.
• The person you are calling is busy on another PTT call or on a cellular call. Please see the
User
Busy on page 164
section for more information.
• Your phone loses connection with the data network or PTT server. Please see the Loss of Data
Network Connection on page 163
section for more information.
• The person you are trying to call is temporarily not reachable. Please see the
User Unreachable
on page 164
section for more information.
22.7
Calls Are Always Heard in the Earpiece
If you are hearing PTT calls through the earpiece instead of the loudspeaker, the speakerphone
ON/OFF setting may be set to OFF. You can change this setting in the application settings or during
a call. To turn on the speakerphone, tap the on-screen speakerphone button to ensure it is ON (shown
by the green indicator on the button). More details are found in the
Call Screen Icons on page 42
section. Another reason may be that your phone ringer is set to Silent. Ensure that your phone is not in
silent mode and check that Privacy Mode is not set to Earpiece. See the
Interaction with Silent or
Sound Mode on page 65
section for more information about interaction with your phone’s silent mode.
22.8
Calls Are Only Received from a Small Number of Groups
If you are receiving calls from only a couple of groups, you may have turned “Talkgroup Scanning” on
and are listening to only the groups in the scan list. More details can be found in the
Talkgroup
Scanning on page 99
section.
22.9
Cannot Change the Phone Number of a PTT Contact
While the name, avatar, color, and favorite status of a contact can be changed, phone numbers cannot
be changed. If you need to change a contact’s phone number, you need to delete the contact and
add it again with the new phone number. Please see the
Contacts on page 86 section for details on
deleting and adding PTT contacts. Contacts that are managed by an administrator cannot be renamed
or deleted.
