Summary:                    IAX Transfer/releasing between 3 asterisk's are not
working.
Description: 
Since the Asterisk Version 1.6.0-beta9 (the first 1.6.0 i tried) i the IAX
Releasing is not working on this machine.
I tried also 1.6.0-rc6 and the problem is still the same.

I have some asterisk 1.2.* and 1.4.* and SVN-trunk-r92976 running, and
with all machines calls are released after the call answered.

Only the machine with asterisk 1.6.0-* can't do this.

i don't know how to test things to help debugging it.

if you need anything to solve this problem, please let me know.

thanks a lot

Nico

---------------------------------------------------------------------- 
I've had a similar issue and IAX debug output for an IAX trunk between two
Asterisk boxes. Both running Asterisk 1.4 but with one running on Zaptel
and the other on Dahdi.

The details of the boxes are;

1.4.18 Asterisk + Zaptel 1.4.8 
    <= IAX trunk =>
1.4.22 Asterisk + Dahdi 2.0

The calls can be made between the boxes without any issues except on the
hangup when the Dahdi extension initiates the hangup. Here the channel on
the other box doesn't see any HANGUP signal and stays open for a few
seconds before hanging up with the following IAX debug (seen on both
boxes);

    Tx-Frame Retry[000] -- OSeqno: 004 ISeqno: 008 Type: IAX     Subclass:
LAGRQ
       Timestamp: 20013ms  SCall: 00001  DCall: 07750
[192.168.71.102:4569]
    Rx-Frame Retry[ No] -- OSeqno: 000 ISeqno: 000 Type: IAX     Subclass:
INVAL
       Timestamp: 00000ms  SCall: 07750  DCall: 00001
[192.168.71.102:4569]

If the Zaptel box initiates the hangup, both boxes hangup immediately with
the following IAX debug;

    *CLI> Rx-Frame Retry[ No] -- OSeqno: 002 ISeqno: 006 Type: IAX    
Subclass: HANGUP
       Timestamp: 08594ms  SCall: 00001  DCall: 06356

       CAUSE CODE      : 16
    
    Tx-Frame Retry[-01] -- OSeqno: 006 ISeqno: 003 Type: IAX     Subclass:

       Timestamp: 08594ms  SCall: 06356  DCall: 00001
[192.168.71.103:4569]
      == Spawn extension (default, 21211, 1) exited non-zero on
'IAX2/swayzak-6356'
        -- Hungup 'IAX2/swayzak-6356'

Is Dahdi compatible with Zaptel for IAX trunking between Asterisk boxes?
