have been provisioned to transmit content to each other within a
specified geographic area(s). Refer to the Iridium Extreme

LISTENING, TALKING and OPEN.
IDLE:

When a talkgroup is active and a participant has the
floor, the devices that are participating in the talkgroup will display
LISTENING.
TALKING:
When a talkgroup is active and a participant has the floor,
the device that has the floor will display TALKING.
OPEN:
When a talkgroup is active but no one has the floor, the
devices that have the talkgroup as their Home Talkgroup will display
OPEN.
