External Event Indicates:
SndMsg_Drop message type via the
cc_SndMsg( ) function.
The CCEV_CONFDROP event has two
different meanings that depend upon the type
of call:
Two-party call - the event is a request to
disconnect the call. The application should
respond by issuing a cc_DropCall( ).
Conference call - the event is a request to
remove the last party that was added to the
conference. The application needs to respond
to this request with either a
SndMsg_DropAck or SndMsg_DropRej
message to indicate the acceptance or
rejection of the request. If the request is
accepted, the party is dropped from the
conference.
The CCEV_CONFDROP event only pertains
to a Custom BRI 5ESS switch type.

the remote end is not ready to accept

Refer to the sample code in the
cc_GetSAPI( ) and cc_GetCES( ) function
