Hi, I'm using it in New York, and we seem to be having good success (on
this particular provider) with:

[general]
initial_silence = 3700
greeting = 2500
after_greeting_silence = 1200
total_analysis_time = 6000
min_word_length = 100
between_words_silence = 50
maximum_number_of_words = 4
silence_threshold = 860

Disclaimer: just use this as a starting point, go into the console with
debug and verbose up, and make sure that for every word you speak, it
recognises a word, then try again with cellphones instead of landlines.

Remember that you're not going to get 100%, some answer machine messages
may have been recorded quietly etc.

You'll need to also make sure that the upstream provider doesn't answer
the call and then provide ringing (as the stanaphone DID we were testing
did).

Report back how you go on this, maybe we should start a wiki page with
settings in different places.
