Summary:                    Chanspy Keeps using G729 Encoder licenses even after
the spying channel hangs up.
Description: 
Hi,

We are using Asterisk 1.6.2.9 and running on Cent OS 5.4 x86_64 kernel
2.6.18-194.3.1.el5

We are using G729 for our sip trunks. Our extensions use G729 as well.
When I try to spy on a channel with chanspy, I observe that the G729
licenses keep getting used up but do not get freed up even when I hang up
the Spy / Spying Extension.

Is there any way we can free up the licenses when the spying of a channel
is over?

When I do g729 show licenses I get the following output.. And with every
channel that is spied on, the encoder count keeps increasing but with every
call that is hung up, the encoder count does not decrease.

2/0 encoders/decoders of 16 licensed channels are currently in use

Licenses Found:
File: G729-REMOVED.lic -- Key: G729-REMOVED -- Host-ID: REMOVED --
Channels: 11 (Expires: 2030-07-01) (OK)
File: G729-REMOVED.lic -- Key: G729-REMOVED -- Host-ID: REMOVED --
Channels: 5 (Expires: 2030-06-28) (OK)

      remove empty audiohook write list on channel
      
      If a channel has an audiohook write list created on it, that
      list stays on the channel until the channel is destroyed.  There
      is no reason to keep that list on the channel if it becomes empty.
      If it is empty that just means we are doing needless translating
      for every ast_read and ast_write.  This patch removes the audiohook
      list from the channel once it is detected to be empty on either a
      read or write.  If a audiohook is added back to the channel after
      this list is destroyed, the list just gets recreated as if it never
      existed to begin with.
