Hi,

  Lately, probably after updating from 1.6.7 to 1.6.9, people are complaining that some faxes are received as voicemail. Indeed I don't see in my logs that the tone detect found the fax CNG tone.

Hence, I have a couple of questions:

- What is the tolerance of tone_detect function?

- If I call it a few times with slightly different frequencies, will all of them trigger, or only the last one?

            Thanks! __Yehavi:
