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.

  IAX2 "Ghost" Channels

  There is a bug tracker issue where people are reporting "Ghost" channels
in their 'iax2 show channels' output.  The confusion is caused by channels
being listed as "(NONE)" with format "unknown".  These are not channels of
coarse.  They are usually just pending registration or poke requests, but
it is confusing output.  To help make sense of this I have added two
columns to 'iax2 show channels'.  One shows the first message which started
the transaction, and the second shows the last message sent by either side
of the call.  This helps diagnose why the entry exists and why it may not
go away.
