[asterisk-users] Answer Machine Detection

Hi all,

    i'm trying to make AMD, Answer Machine Detection, to work on my 
outbound context but i can't get it to work, just on inbound context 
like whe i use the application Answer before AMD, but i need to make AMD 
to do the detection on an outbound predictive dialer integration. Follow 
are the inbound and outbound examples. My current environment is 
Asterisk 1.4beta3 and a Digum TE105P with ISDN E1. Have any one managed 
to do answer machine detection already?

[outbound]
exten => _x.,1,AMD
exten => _x.,2,Dial(SIP/${EXTEN}@10.1.1.203,,tT)
exten => _x.,3,Wait(2)
exten => _x.,4,Set(RECORDEDFILE=${CALLERID(num)}.wav)
exten => _x.,5,Record(${RECORDEDFILE},,,skip)
exten => _x.,6,Hangup

[inbound]

exten => _x.,1,Answer
exten => _x.,2,AMD
exten => _x.,3,Wait(2)
exten => _x.,4,Set(RECORDEDFILE=${CALLERID(num)}.wav)
exten => _x.,5,Record(${RECORDEDFILE},,,skip)
exten => _x.,6,Hangup



My AMD conf

;
; Answering Machine Detection Configuration
;

[general]
initial_silence = 2500              ; Maximum silence duration before 
the greeting.
                                              ; If exceeded then MACHINE.
greeting = 1500                      ; Maximum length of a greeting. If 
exceeded then MACHINE.
after_greeting_silence = 300   ; Silence after detecting a greeting.
                                              ; If exceeded then HUMAN
total_analysis_time = 5000      ; Maximum time allowed for the algorithm 
to decide
                                              ; on a HUMAN or MACHINE
min_word_length = 120          ; Minimum duration of Voice to considered 
as a word
between_words_silence = 50  ; Minimum duration of silence after a word 
to consider
                                               ; the audio what follows 
as a new word
maximum_number_of_words = 3     ; Maximum number of words in the greeting.
                                                       ; If exceeded 
then MACHINE
silence_threshold = 256

What predictive dialer are you using? How does it make outbound calls?

There is a patch available for 1.2 that we have been uusing for
several months if you want to use release-quality Asterisk.

I had a hell of a time getting AMD to work correctly on 1.4. If I didn't
compile asterisk correctly (I'm not sure how I was doing it incorrectly), it
wouldn't work (and would just stop the dialplan execution). Try recompiling
everything (make clean && make install) and see if that helps. (It's
working
fine for me now...)


FYI, AMD will not Wait() for the answering machine to finish talking. It
will only set some status variables, with which you should use
WaitForSilence() afterwards to wait for everything to get 'quiet'

    AMDSTATUS - This is the status of the answering machine detection.
                Possible values are:
                MACHINE | HUMAN | NOTSURE | HANGUP
    AMDCAUSE - Indicates the cause that led to the conclusion.
               Possible values are:
               TOOLONG-<%d total_time>
               INITIALSILENCE-<%d silenceDuration>-<%d
initialSilence>
               HUMAN-<%d silenceDuration>-<%d afterGreetingSilence>
               MAXWORDS-<%d wordsCount>-<%d maximumNumberOfWords>
               LONGGREETING-<%d voiceDuration>-<%d greeting>
