<div>KPML is now an RFC -- <a href="http://www.ietf.org/rfc/rfc4730.txt ">http://www.ietf.org/rfc/rfc4730.txt </a></div>

<div>Asterisk doesn't support KPML today. That doesn't mean it can not be developed if there is sufiicient interest. The true value of adding KPML support in Asterisk is when it is acting as a 'softswitch' (call controller without media hairpin) such that it can install a digit map and collect digits from end-points over the signaling path.
