Summary:                    app_amd doesnt works properly
Description: 
Hi 

We are using Asterisk 1.2.24 , zaptel 1.2.21 and libpri 1.2.4 , we have
compiled app_amd.c in the way we should and got our amd detection parameter
working .

The problem which we are facing majorly is AMD detection is not good and
also NO ANSWERS calls are in huge ratio.

We have debug the problem and found that NO ANSWERS are nothing but
actually a answering machine like voicemail and that gets transferred to
the agents and till the time it gets transfer voice mail gets finished and
that call is treated as a NO ANSWER .


The AMD parameter which we are working is 


[amd]
initial_silence = 3500
greeting = 1500
after_greeting_silence = 800
total_analysis_time = 5000
min_word_length = 120
between_words_silence = 50
maximum_number_of_words = 2
silence_threshold = 256


If we decrease the after greeting silence to 300 , then amd detection goes
low and lot's of answering machines comes to the agents .


Is there any way of solving this problem .


Any one who is working with this app_amd parameter and not facing no
answer problem , do let me know plz 


That would be of great help.

garrygarry6628,

 Asterisk 1.2 is on security maintenance mode now, would you be able to
check if you can reproduce it on * 1.4 ?
