(Note: A preferred volume range is -8 dBm0 to -3 dBm0.) The duration of the tone in milliseconds. The tone starts when the method call is received and lasts for the duration value. The value 0 indicates indefinite duration, the tone is played until StopTone() is called.

Description of tone. The power level of the tone with range from 0 to -63 dBm0. (Note: A preferred volume range is -8 dBm0 to -3 dBm0.) The duration of the tone in milliseconds. The tone starts when the previous tone ends and lasts for the specified duration. The value 0 indicates indefinite duration, the tone is played until StopTone() is called. The modulation frequency in Hz. If there is no modulation, this field has a value of zero. The frequencies of the tones to be added, measured in Hz. A value of zero or an empty array indicates silence.
