<p>Hi, you just have to use delegates to asynchronously call the function
containing the loop and return back the control to the calling thread. Here an
example (don't have my code at hand, hope it doesn't contain typos).</p>

<p>Is there a way to start this when FreeSWITCH starts? The lua and perl
modules have a 'startup-script' configuration preference. Is there something
similar in mod_managed? Or is there a way to have an api command executed at a
startup?</p>
