asterisk users - Sep 2010 - problem with iax call (chan unavailable)

Hi,

I have a problem with my IAX softphones. After a call, when the softphone
hangup, it remains unavailable for the other softphones. It can call anybody,
but can not be reached... For example, if A call B, B answer, then  A or B
hangup, and C won't be able to call A or B after that (but A or B would be
able
to call C). The Dial function returns that the chan is unavailable. That is very
annoying, the only solution till now is to restart my softphones.... I must say
that sometimes it works fine and i do not encounter this problem. But it happens
very regularly, too often i would say.

I would like to know if some of you noticed that problem ? And if there is a
solution of course...
I tried with different sofphones : iaxlite, or other i do not remember the
name... I also have the sources of iaxComm (an open source softphone from
iaxclient project), do you think it could be a softphone problem, and if i can
do something to change the code....

To illustrate my problem, here is the full output of a failed call-back:
http://pastebin.com/FMeL3mYz

For this test, the extensions.conf was really minimum :
[default]
exten => 222,1,Dial(IAX2/bob.test.org)
exten => 222,2,Hangup()
exten => 111,1,Dial(IAX2/alice.test.org)
exten => 111,2,Hangup()

I use Asterisk 1.6.2.11 (i had the same problem with 1.6.2.6).

Thanks for you help.

Try it with Zoiper and see how you go.  I've not seen the same thing happen.

It may also be that you are using qualify and that the peer is too far away.

What do you get when you type iax2 show peers?
