I would be interested in seeing this code, as I have found that the hangup signal I get lasts for an exact amount of time before the line goes silent, so if I time it precisely, I may be able to adapt the code to only trigger if the tone lasts greater than a certain amount but less than another amount, which should prevent it triggering on voices (as it is about 4 seconds and the likelihood of that tone coming from a female voice and lasting 4 seconds is slim).
