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 Configuration → Manual Editor → Answering Machine Detection
Parameters
Time values are all in milliseconds unless stated otherwise.
- initial_silence is the maximum silence duration before the greeting. If exceeded then MACHINE.
- greeting is the maximum length of a greeting. If exceeded then MACHINE.
- after_greeting_silence is the silence after detecting a greeting. If exceeded then HUMAN.
- total_analysis_time is the maximum time allowed for the algorithm to decide on a HUMAN or MACHINE.
- min_word_length is the minimum duration of Voice to considered as a word.
- between_words_silence is the minimum duration of silence after a word to considere the audio what follows as a new word.
- maximum_number_of_words is the maximum number of words in the greeting. If exceeded then MACHINE.
- silence_threshold is the silence threshold.
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
