If, however, you are using twisted, I would just do something like the following:<br>

</div><div class="gmail_extra"><br></div><div class="gmail_extra">Or you can make Asterisk perform the pause:<br><br></div><div class="gmail_extra">chan.play(media='sound:silence/1')<br><br></div><div class="gmail_extra">
Since ARI queues up sounds, that will automatically either (a) play 1 second of silence immediately, or (b) play 1 second of silence whenever the current media operation finishes.<br></div><div class="gmail_extra"><br>[1] <a href="https://docs.python.org/2/library/threading.html#timer-objects">https://docs.python.org/2/library/threading.html#timer-objects</a><br>
