Summary:                    iax2 trunked channels not being cleared
Description: 
It appears to me as a memory leak, as many old iax2 channels are appearing
in the "iax2 show netstats" as:
(None)                    1000    0   40     0   0     0    0      0    0 
  0     0   0     0    0      0

At present I see 36 out of 57 of these channels reported on "iax2 show
netstats", but when I do a "show channels" there are only 21 calls.

In my humble opinion, something on the channel is not being closed
properly at the end of a call.
Before I was using version 1.2.6 and had no issue at all. I know its been
a long time since then, but I know something is now broken, although I am
not sure which is the latest version which has this behavior.

If I leave asterisk to run on its own, after 1 week there are about 60 of
these ghost channels displayed, and the number keeps increasing with time.

I had to restart Asterisk after changing the iax.conf file to get rid of
the zombie channels.

Here's my iax.conf file:

; Inter-Asterisk eXchange driver definition
;
; This configuration is re-read at reload
; or with the CLI command
;       reload chan_iax2.so
;
; General settings, like port number to bind to, and
; an option address (the default is to bind to all
; local addresses).
;
[general]
iaxcompat=no
nochecksums=no
delayreject=yes
language=en
bandwidth=high
disallow=all
allow=ulaw
allow=gsm

jitterbuffer=yes
forcejitterbuffer=no
maxjitterbuffer=1000
maxjitterinterps=10
resyncthreshold=1000

minregexpire = 120
maxregexpire = 300

iaxthreadcount = 256
iaxmaxthreadcount = 256
autokill=yes
maxauthreq=10
authdebug=no

=====================================

I dnot get zombie channels that stays forever. With this config in
1.4.21.2, I get a few zombie channels that expires which is normal for IAX2
(I think!).

Cheers.
