(06:04:44 PM) rmudgett: lmadsen, dvossel That crash is in Playback because
PickupChan has masqueraded the channel away.  The tech pointer is NULL.

(06:05:29 PM) dvossel: how is the sip_setoption function getting called on
a masqueraded channel

(06:06:16 PM) rmudgett: PickupChan returns zero so the dialplan keeps
executing.  The masquerade has been setup and happens while Playback is
setting up.

(06:06:43 PM) rmudgett: Thus Playback tries to playback a file on a
ZOMBIE.

(06:07:15 PM) dvossel: I thought ZOMBIES were hungup ?!

(06:07:16 PM) rmudgett: I think a quick fix might be to have PickupChan
return nonzero if the Pickup was successful.

(06:07:31 PM) rmudgett: ZOMBIES have not been destroyed yet.

(06:08:10 PM) dvossel: but if it gets hungup in pickupchan, then why does
it go to do the playback

(06:08:11 PM) rmudgett: Their guts have been extracted by the masquerade.
(06:08:30 PM) rmudgett: PicupChan returns zero not nonzero.
(06:09:12 PM) rmudgett: The main PBX execution loop does not check to see
if the channel is a ZOMBIE or setup for masquerade.
(06:09:21 PM) rmudgett: i think.
