For many of the core Connection objectstates, the CallControlConnection interfaces often provides several sub-states of the core states. These sub-states provide more information toapplication about what is going on. The method getCallControlState() returnsthis more detailed state. Typically, applications with either monitorthe core Connection states or the CallControlConnection states.<p>The Connection states presented by this interface are: IDLE, OFFERING,QUEUED, NETWORK_REACHED, NETWORK_ALERTING, ALERTING, INITIATED, DIALING, ESTABLISHED, DISCONNECTED, FAILED, BUSY, UNKNOWN.<p>The real-world definitions for these states follow. Note that thesedefinitions are not technical nor absolute, however, they give an ideato the reader about what these states means:<p>The IDLE state is defined similiarly here as it is in the core. The IDLEstate is the initial and transitory state for new Connection objects.<p>The OFFERING state is particular to ISDN and indicates that a Call isbeing offered. Typically, applications must accept or reject this offeredcall.<p>The QUEUED state indicates that a Connection is queued at a particularaddress. This may result when someone enables the queueing mechanism onan address and the address is busy when a telephone call comes in.<p>The NETWORK_REACHED state indicates that the outgoing telephone call hasreached the network, however, further events may not be received. It isup to the application whether to treat this as a connected call.<p>The NETWORK_ALERTING state indicates that the outgoing telephone call haspreviously reached the network, however, further information obtained fromthe switch indicates that this call is now alerting at some destinationendpoint.<p>The ALERTING state has the same definition as in the core.<p>The INITIATED state indicates that an originating Connection's telephoneis off-hook, however, dialing has not yet begun.<p>The DIALING state applies to originating Connections and indicates thatthe process of dialing has begun but has not yet completed.<p>The ESTABLISHED state has a similar definition as CONNECTED does in the core.It indicates that a Connection has reached its final active state in thecall.<p>The DISCONNECTED state has the same definition as in the core.<p>The FAILED state has the same definition as in the core.<p>The UNKNOWN state has the same definition as in the core.<p>These CallControlConnection states are defined in terms of the coreConnection states. In other words, if the core Connection is in a particularstate, then the CallControlConnection must be in one of possible severalstates. This relationship is defined below, where the core Connection statesare on the left, and the CallControlConnection states are on the right.<p><UL><LI>IDLE ---> IDLE<LI>INPROGRESS ---> QUEUED,
