This application attempts to detect answering machines at the beginning of outbound calls. It is used in a variety of ipbx application to detect answering machines. AMD settings can be configured in the Administrator Panel under ConfigurationManual EditorAnswering Machine Detection

Parameters

Time values are all in milliseconds unless stated otherwise.

Example AMD Configuration

You can copy the values below directly into the Manual Editor and adjust according to your needs:

 [AMD] 
 initial_silence = 2500 
 greeting = 1500 
 after_greeting_silence = 300 
 total_analysis_time = 4000 
 min_word_length = 120 
 between_words_silence = 50 
 maximum_number_of_words = 5 
 silence_threshold = 256
