detected to be valid if (BTON – BTOD < on time <
BTON + BTOD) and (BTOF – BTOD < off time < BTOF
+ BTOD).

RTOF
Ringback tone off. Time that the ringback tone must be
off (53.333 ms units) for ringback tone detector.
0x4B
S1B
0x1B
RTOD
Detector time delta (53.333 ms units). A ringback tone
is determined to be valid if (RTON – RTOD < on time <
RTON + RTOD) and (RTOF – RTOD < off time < RTOF
+ RTOD).
