LINEDIALTONEMODE (Compact 2013)
3/26/2014
These bit-flag constants describe different types of dial tones. A special dial tone typically carries a special meaning (as with message waiting).
The following table shows the LINEDIALTONEMODE constants.
Value |
Description |
|---|---|
LINEDIALTONEMODE_EXTERNAL = 0x00000008 |
This is an external (public network) dial tone. |
LINEDIALTONEMODE_INTERNAL = 0x00000004 |
This is an internal dial tone, as within a PBX. |
LINEDIALTONEMODE_NORMAL = 0x00000001 |
This is a normal dial tone, which typically is a continuous tone. |
LINEDIALTONEMODE_SPECIAL = 0x00000002 |
This is a special dial tone indicating that a certain condition, known by the switch or network, is currently in effect. Special dial tones typically use an interrupted tone. As with a normal dial tone, this indicates that the switch is ready to receive the number to be dialed. |
LINEDIALTONEMODE_UNAVAIL = 0x00000020 |
The dial tone mode is unavailable and will not become known. |
LINEDIALTONEMODE_UNKNOWN = 0x00000010 |
The dial tone mode is not currently known but may become known later. |
Remarks
The high-order 16 bits can be assigned for device-specific extensions. The low-order 16 bits are reserved.
The LINEDIALTONEMODE_ constants are used within the LINECALLSTATUS data structure for a call in the dialtone state.
