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 :(

So I don't have a license agreement and system not letting me to post the
diff.  Now I do not have time to deal with licensing. And what I don't
understand is what is our goal - is it to have me sign an agreement or to
fix the regression, which I pointed out exactly and what could be fixed by
any of the developers, since there is a few lines of the code,reverted from
1.4.21.2?
