6. CALL TYPES
The Trunking System allows the user to make a number of different types of call. The
SRM9030plus supports most of the call types that can be accessed through the Trunk
Network, including:
•
Voice calls between Individuals or Groups
•
Include Calls
•
Status Calls
•
Priority and Emergency Calls
•
Diversion Calls
•
Broadcast Calls.
Individual Calls. Allow private conversations between two users. Other users can be
included in the call using an Include Call.
Group Calls. Allow different members of a group to participate in a group conversation. Any
participant in the group can leave the call individually, but only the originator can end the call.
Status Calls. Allow a status number to be sent between users. The SRM9030plus allows
text messages to be associated with up to 30 status numbers and can display these text
messages when such a status is to be sent or is received.
Diversion Calls. Allow the user to divert incoming calls to another radio, telephone, etc.
Additionally the SRM9030plus can call radios that are similarly diverted. For example, when
away from their vehicle, a user can divert calls to the depot radio.
Normal, Priority and Emergency Calls. If the channel is busy, Normal calls are placed in a
queue and actioned when they reach the top of the queue. Priority calls jump to the top of
the queue unless a previous priority call is taking place. Emergency calls are actioned
immediately.
Broadcast Calls. Are similar to Group calls except that only the initiator of the call can
speak to the other parties in the call.
Notes 1: Some of these call types are only available after prior arrangement with the
Network Operator.
2: Most Trunk Networks have a time limit placed on call duration. The Network
terminates the call after this time.
