<div dir="ltr">Hi All,<br><br>I've been asked by a prospect if Asterisk can handle the additional DTMF signals that <br>may be produced by some emergency systems. According to the DTMF standard,<br>there are 4 additional tones that can be generated, however, these are not used in most<br>
phones. <br><br>Can these be intercepted by Asterisk?<br><br>Nir Simionovich<br><br></div>
