Send Feedback

These bit-flag constants describe the origin of a call.

The following table shows the LINECALLORIGIN constants.

Value Description
LINECALLORIGIN_CONFERENCE = 0x00000040 The call handle is for a conference call. That is, it is the application's connection to the conference bridge in the switch.
LINECALLORIGIN_EXTERNAL = 0x00000004 The call originated as an incoming call on an external line.
LINECALLORIGIN_INBOUND = 0x00000080 The call originated as an incoming call, but the service provider is unable to determine whether it came from another station on the same switch or from an external line. Service providers can use this constant only when TAPI version 1.4 or later has been negotiated. Otherwise, the service provider can substitute LINECALLORIGIN_UNAVAIL.
LINECALLORIGIN_INTERNAL = 0x00000002 The call originated as an incoming call at a station internal to the same switching environment.
LINECALLORIGIN_OUTBOUND = 0x00000001 The call originated from this station as an outgoing call.
LINECALLORIGIN_UNAVAIL = 0x00000020 The call origin is not available and will never become known for this call.
LINECALLORIGIN_UNKNOWN = 0x00000010 The call origin is currently unknown but may become known later.

Remarks

These constants cannot be extended. All 32 bits are reserved.

The origin of a call is stored in the dwOrigin member of the call's LINECALLINFO structure.
