LINECALLORIGIN (Compact 2013)

3/26/2014

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.

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.
