While I don't know of any perl-centric solutions to the problem of DTMF recognition beyond using PDL to implement a Fast Fourier Transform of some sort, to determine frequency and mapping that to a list of frequencies/dtmf tones... There is a library called 'amTapi', that's fully TAPI compliant. amTapi purports to support DTMF detection and playback of wave files to telephony devices (among other features). It's written in C++, but you could (most likely) easily interface to it using XS. If you do happen make an XS interface, please share! =)
At any rate, since you're on windows, you should *definately* read up on TAPI which is the standard API for telephony devices under Win32.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
