and when the called party has no available contact, the calling instruction is not executed.

When the called party is in idle state, the call is directly connected and the called party rings.

If the called party is in a conversation state at present, in order to avoid the potential safety hazard caused by the missed connection of the telephone called from the dispatching desk, a forced insertion means is adopted to connect the conversation between the called party and the dispatching desk according to the principle that the calling priority initiated by software of the dispatching console is the highest.

Taking the example that the group-level dispatching desk initiates a group call to the mine-level dispatching desk, the group call process is as shown in fig. 4 below.

(5) Forced insertion:

the dispatching desk is a dispatching user with a break-in function and authority, and when the called party is in a conversation state, the dispatching desk can directly join the established conversation of the called party by using the break-in function to further form three-party conversation, so that the production dispatching safety is ensured.

Taking the example that the group-level dispatching desk initiates the break-in to a certain dispatching terminal at the mine level, the break-in flow is as shown in fig. 5 below.

(6) Forced dismantling:

the dispatching desk has a forcible entry function and a dispatching user with authority, when the called party is in a conversation state, the dispatching desk can directly terminate the conversation established by the called party by using the forcible entry function and further connect the conversation between the dispatching desk and the called party, so that the safety of production dispatching is ensured.

Taking the example that the group-level dispatching desk initiates the forced demolition to a certain dispatching terminal at the mine level, the forced demolition flow is as shown in fig. 6 below.

(7) Call forwarding

The dispatching desk has the dispatching user of call transfer function and authority, when the dispatching desk needs to transfer the call to another dispatching termination equipment, the call transfer function can transfer the conversation to the third party.

Taking the example that the group-level dispatching desk initiates manual switching to a certain dispatching terminal at the mine level, the manual switching process is as shown in fig. 7 below.

When listening, the listener can not hear the sound of the side of the listener.

Taking the example of the group-level dispatching desk monitoring the mine-level dispatching conversation, the monitoring process is as shown in fig. 9 below.
