LINEBUSYMODE (Compact 2013)

3/26/2014

These bit-flag constants describe different busy signals that the switch or network can generate. These busy signals typically indicate that a different resource that is required to make a call is currently in use.

The following table shows the LINEBUSYMODE constants.

Value

Description

LINEBUSYMODE_STATION = 0x00000001

The busy signal indicates that the called party's station is busy. This is usually signaled with a normal busy tone.

LINEBUSYMODE_TRUNK = 0x00000002

The busy signal indicates that a trunk or circuit is busy. This is usually signaled with a fast busy tone.

LINEBUSYMODE_UNKNOWN = 0x00000004

The busy signal's specific mode is currently unknown but may become known later.

LINEBUSYMODE_UNAVAIL = 0x00000008

The busy signal's specific mode is unavailable and will not become known.

Remarks

The high-order 16 bits can be assigned for device-specific extensions. The low-order 16 bits are reserved.

Note

Busy signals can be sent as inband tones or out-of-band messages. TAPI makes no assumption about the specific signaling mechanism.
