LINEBUSYMODE_ Constants
The LINEBUSYMODE_ 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.
-
LINEBUSYMODE_STATION
-
-
The busy signal indicates that the called party's station is busy. This is usually signaled with a normal busy tone.
-
-
LINEBUSYMODE_TRUNK
-
-
The busy signal indicates that a trunk or circuit is busy. This is usually signaled with a fast busy tone.
-
-
LINEBUSYMODE_UNKNOWN
-
-
The busy signal's specific mode is currently unknown but may become known later.
-
-
LINEBUSYMODE_UNAVAIL
-
-
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.
