Return is invalid unless
ANSWER_DETECT is called prior to calling ANSWER_DEBUG |
Returns a number that indicates the exit point from the
ANSWER_DETECT routine.This function is useful in determining
proper settings of parameters to the ANSWER_DETECT routine.
Ret Answer Exit Condition
1 5 Timeout, 30 seconds and no ring or busy received
2 5 Timeout, 60 seconds and no speech detected is enabled
3 4 Keystroke, a key was pressed and KEYBD_INT is enabled
4 0 speech detect, silence > busy interval and double
ring interval after apparent busy detected
5 0 Speech detect, silence > ring interval after apparent
ring or busy detect
6 0 Speech detect, tone < ring detected after prev ring
7 0 Speech detect, tone < busy detected after
previous busy or ring detected
8 1 Max rings, double ring count > ring argument
9 2 Max busies, busy count > busies (4)
10 1 Max rings, ring count > ring argument
11 0 Speech detect, deviation of signal > sensitive * 8
12 5 Timeout, operator intercept was detected
13 0 Speech detect, signal > 2.5 seconds longer than
longest call progress tone
Ret = return code from ANSWER_DEBUG
AD = return from ANSWER_DETECT
The < > and = characters refer to comparisons of lengths of
tones and intervals detected in the answer detect algorithm.
