If the NaturalAccess NaturalCallControl API (NCC API) is active, and a protocol was started on a line using nccStartProtocol, call control proceeds as described in the Dialogic® NaturalAccess™ NaturalCallControl™ API Developer’s Manual. This section outlines NCC API call control from an ISDN Software point of view. It contains:
Descriptions of NCC API functions and associated events, when used with ISDN Software.
