[Freeswitch-users] Canceling sched_hangup and UUID lookup

Tue Jan 6 20:09:22 MSK 2015

For posterity's sake I thought it would be good to drop a few tidbits here.

#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?

#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.

Hope this helps.
