Notes:
Clear Call Service
This service will cause each device associated with a call (C1) to be released. The conditions
applied to individual extensions concerning the Clear Connection Service apply to each con-
nection in the call.
Function: cstaClearCall(), CSTAClearCallConfEvent
Direction: C → S
Functional Description:
DBS-92-470
•
NO_CALL_TO_ANSWER (28)
The specified connection at the station is not alerting.
•
MISTYPED_ARGUMENT_REJECTION (74)
DYNAMIC_ID is specified in alertingCall.
•
RESOURCE_OUT_OF_SERVICE (34)
The DBS is off-line.
•
OUTSTANDING_REQUEST_LIMIT_EXCEEDED (44)
The application has too many outstanding CSTA requests.
•
GENERIC_UNSPECIFIED (0)
An internal driver error has occurred.
•
If the station user is on-hook idle, the switch will turn on the speaker/headset and
answer the call.
•
If the station user is busy on a call, the current call with either be put on hold or
dropped depending on the "key-bank-hold" option setting.
The Clear Call Service disconnects all connections from the specified call and terminates
the call itself. All connection identifiers previously associated with the call are no longer
valid. It should be noted that the DBS in itself does not support the cstaClearCall function
-- instead the Panasonic Telephony Services driver converts the cstaClearCall function
into individual cstaClearConnection functions. The driver makes every attempt to verify
that all the cstaClearConnection commands will succeed; however in some cases (e.g., the
extension is physically off-hook), the call will not be cleared even though a positive con-
firmation is returned to the application.
