<div dir="ltr"><div><div><div>For posterity's sake I thought it would be good to drop a few tidbits here.<br><br></div>#1 - You *can* delete a scheduled hangup. You just need to know the task number. When you issue the sched_hangup you'll see the task id printed on the console. You can also get a list of the scheduled tasks by issuing the "show tasks" API. Once you know the task id you can simply do "sched_del <task id>". Piece of cake, no?<br><br></div>#2 - If you aren't using the presence_data field for anything else, which in your case you probably are not, you can set info there. Just do a set or export prior to the bridge or add "{presence_data=foo}" to the beginning of the dialstring. From there you can just do "show channels like foo" and you'll get only those channels. Just be sure to have your presence_data value be very specific so that you don't accidentally grab unwanted channels.<br><br></div><div>Hope this helps.<br></div><div>-MC<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 2, 2015 at 3:00 PM, Kurtis Heimerl <span dir="ltr"><<a href="mailto:kheimerl@cs.berkeley.edu" target="_blank">kheimerl@cs.berkeley.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I think I understand how it could be done through ESL, but there's no mechanism to look up sessions?
