Emergency Mode has higher priority then Call-out. When the user receives the alert, three
responses are available:

before the Call-out.

8.1.2 CO Box (Call-Out Box)
All incoming and outgoing Call-out messages are stored in CO Box and can be managed by the
user. There is a two- level structure for the alerts. First level is the main alert list, as the second one
are all the messages associated with the alerts. Both lists are displayed chronologically with the
newest on top. The capacity of the CO Box is 10 call-out alerts and 100 messages (incoming/
outgoing). It has also the overwrite policy which will delete the oldest one upon receipt of an
additional Call-Out message.
In normal mode, the user can browse the CO Box and read all the Call-Out messages.
In Call-Out mode, user can only read the ongoing Call-Out messages.
8.1.3 New Call-Out
When the new Call-Out is received by the terminal, the old Call-Out (even if has not been
responded) will override the old one. An ongoing Call-Out overrides the old one in any phase of the
Call-Out alert.
8.2 Phases
Call-Out service has 2 main phases:
1. Alert Phase
User receives the alert with the associated messages and he/she is able to respond to it.
Special tone is played by the terminal when the alert is coming. All the messages provide the
user with all important information about the incident.
2. Information Phase
User is in Call-Out mode and is able to receive more messages about the incident with the
text or voice. User can also query for more information using voice group call or Call-Out text
function which enables to send a text message to the dispatcher host application. Voice
message can be sent with the high priority as a group call. Users can answer back to the
group or to the dispatcher using voice group call.
