ASAI and Call Control
4-74 Issue 7 May 1998
Third Party Call Ended
The ECS uses this terminating capability to inform the adjunct that a controlled
call has ended and to clear the call control association that was controlling the
call. It is also used when two calls are merged since one call control association
terminates when the calls merge.
Information Flow
The ECS does not expect a response.
Third Party Call Ended Parameters
Causes
The ECS issues one of the following reasons as the cause for ending the
association.
■ Normal clearing (CS0/16)
The call having the requested call identity has been cleared. The call is no
longer active. The extraneous call is dropped as the result of merging the
call.
■ User busy (CS0/17)
The first alerted party on the call is busy and the call is dropped.
■ Classifiers not available (CS3/21)
— The call is dropped because no call classifiers are available.
— COR check failed.
■ Call with requested identity has been terminated (CS3/86)
Two calls have been merged into one.
■ Trunks not available (CS3/20)
The call is dropped because no trunks are available.
■ Split Queues full (CS3/22)
The call is dropped because it cannot be queued.
■ Denial/Reorder (CS0/42)
The reorder tone is detected.
■ Outgoing calls barred (CS0/52)
The calling party number of a Switch-Classified call has an FRL lower than
that of the trunk group.
