Call Acknowledgement Configuration
Note:
This functionality applies to E1, T1 and ISDN technologies only.
When an incoming call is received, an acknowledgement is typically sent to the remote side to
indicate that the call was received. In some technologies, if the incoming call does not have
sufficient information, this acknowledgement also indicates to the remote side that more
information is required to proceed with the call (see
indicate that the call was received. In some technologies, if the incoming call does not have
sufficient information, this acknowledgement also indicates to the remote side that more
information is required to proceed with the call (see
for more
information). Either the technology call control layer or the application can be configured to send
the acknowledgement. This configuration can be set by the application issuing the
gc_SetConfigData( ) function. The set ID used in this context is GCSET_CALL_CONFIG and the
relevant parm ID is:

Call Proceeding Configuration
When an incoming call is received and all the information required to proceed with the call is
available, an indication that the call is proceeding is usually sent to the remote side for
informational purposes. Either the technology call control layer or the application can be
configured to send a call proceeding indication to the remote side. This can be done by issuing the
gc_SetConfigData( ) function. The set ID used in this context is GCSET_CALL_CONFIG and the
relevant parm ID is:
