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 :(

The same for me, I've lost 2 days switching contexts and so on, trying to
find out what's happening with my dialplan, then finally switched from
1.4.22 to 1.4.21.1 - which got me normal behaviour. na d than found this
bug file...
