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.
