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.

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.
