I am using Asterisk 1.8 on Ubuntu. the problem is however I change the amd.conf configurations AMD() call detects AMDSTATUS as MACHINE. Please guide me on the right settings for AMD detection if a person picks up phone and says 'Hi this is so and so' vs. machine picks up with a 10-19 minute message followed by a beep. I am willing to pay if some one can solve this for me.
Here is my amd.conf settings:
[general]
initial_silence = 2250 ; Maximum silence duration before the greeting.
; If exceeded then MACHINE.
greeting = 15000 ; Maximum length of a greeting. If exceeded then MACHINE.
after_greeting_silence = 2250 ; Silence after detecting a greeting.
; If exceeded then HUMAN
total_analysis_time = 25000 ; Maximum time allowed for the algorithm to decide
; on a HUMAN or MACHINE
min_word_length = 300 ; Minimum duration of Voice to considered as a word
between_words_silence = 250 ; Minimum duration of silence after a word to consider
; the audio what follows as a new word
maximum_number_of_words = 8 ; Maximum number of words in the greeting.
; If exceeded then MACHINE
silence_threshold = 500
here is my extensions.conf setting for this extension:
[AMDTEST]
exten=> s,1,Answer()
exten=> s,n,AMD()
exten=> s,n,NoOp(${AMDSTATUS})
exten=> s,n,GotoIf($[${AMDSTATUS}=HUMAN]?humn:mach)
exten=> s,n(mach),WaitForSilence(3000,1,20)
exten=> s,n,Playback(${VOICEFILE})
exten=> s,n,Hangup()
exten=> s,n(humn),WaitForSilence(500)
exten=> s,n,Playback(${VOICEFILE})
exten=> s,n,Hangup()
Output in Asterisk debug when I picked up the call and said 'Hi its me here'
