LINETONEMODE (Windows Embedded CE 6.0)
1/6/2010
These constants describe different selections that are used when generating line tones.
The following table shows the LINETONEMODE constants.
| Value | Description |
|---|---|
LINETONEMODE_BEEP = 0x00000008 |
The tone is a beep, such as that used to announce the beginning of a recording. Exact definition is service-provider defined. |
LINETONEMODE_BILLING = 0x00000010 |
The tone is a billing information tone such as a credit card prompt tone. Exact definition is service-provider defined. |
LINETONEMODE_BUSY = 0x00000004 |
The tone is a busy tone. Exact definition is service-provider defined. |
LINETONEMODE_CUSTOM = 0x00000001 |
The tone is a custom tone defined by its component frequencies, of type LINEGENERATETONE. |
LINETONEMODE_RINGBACK = 0x00000002 |
The tone is ringback tone. Exact definition is service-provider defined. |
Remarks
The high-order 16 bits can be assigned for device-specific extensions. The low-order 16 bits are reserved.
These constants are used to define tones to be generated inband over a call to the remote party. Note that tone detection of non-custom tones does not use these constants.
