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 :(

vazir: If you have a fix, that's great, but all code submissions have to be
properly licensed, otherwise there could be potential legal issues for us.
I can assume that by posting code at all you are implicitly giving license
to use it in Asterisk, but without explicitly signing the license
agreement, we cannot use it or even view it. I'm sorry about the
inconvenience it may cause, but it's a one-time agreement to sign and it
does not take long.
