  40. <p>Plays back <em>filename</em>, waiting for interruption from a given digit (the digit must start the beginning of a valid extension, or it will be ignored). During the playback of the file, audio is monitored in the receive direction, and if a period of non-silence which is greater than <em>min</em> ms yet less than <em>max</em> ms is followed by silence for at least <em>sil</em> ms, which occurs during the first <em>analysistime</em> ms, then the audio playback is aborted and processing jumps to the <em>talk</em> extension, if available.</p>
