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.
