Summary:                    chan_iax2 isn't using HANGUP anymore?
Description: 
After upgrading to 1.4.22 problem with call disconnection appeared.

Scenario: 

IP_PHONE <---sip---> ASTERISK_1 <----iax2----> ASTERISK_2 <---zap--->
PSTN

Call from IP_PHONE to PSTN to non_existing number (unassigned/unallocated
number, release cause 1) is no longer cleared immediately, but only after
approx. 10s.
iax2 debug shows, that there is no HANGUP message sent by ASTERISK_2.
Side effect - there is impossible to discover HANGUPCAUSE on ASTERISK_1,
cause HANGUPCAUSE is transmitted in HANGUP message :-(.

In fact, it looks, that there is HANGUP missing in case call was answered,
too.

I'm pretty sure, in 1.4.21.2 it worked. But I have no chance to rolback to
1.4.21.2 right now :(

Revert revision 132506, since it occasionally caused IAX2 HANGUP packets
not
to be sent, and instead, schedule a task to destroy the iax2 pvt structure
10 seconds later.  This allows the IAX2 HANGUP packet to be queued,
transmitted, and ACKed before the pvt is destroyed.
