This is an implementation of Asterisk's answering machine detection (voice activity detection) for FreeSWITCH.

Currently, in limited testing, we are about to get satisfactory results in determining what is a human and what is a machine, but there is much more to do:

• Emit events when a decision is made (Not sure, Machine, or Human).
• Make sure that we are unlocking and cleaning up where necessary.

To build this module, all you need to do is type make, but because it relies on pkg-config and FreeSWITCH, you need to point pkg-config to where FreeSWITCH is installed before building:

host$ export PKG_CONFIG_PATH=/usr/local/freeswitch/lib/pkgconfig/
host$ make
