Probably not. If you have an algorithm in mind that would achieve this with a
high degree of reliability, I'm sure the FreeSWITCH developers would be
interested in it. However, as far as I know, there is no reliable way to
distinguish, for example, my voice as recorded in a voicemail greeting from my
voice giving a live greeting after answering a phone call. Think about it.
