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.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
