Summary:                    [patch] Call to a FXS DAHDI channel with Panasonic
KX-TG4000 connected drops in 8 seconds randomly
Description: 
More often than not a call placed to a DAHDI channel with Panasonic
KX-TG4000 connected would drop on its own in exactly 8 seconds after being
answered. Before being disconnected two (2) clicks are being heard in
succession. The second click kills the connection.

Uploaded dahdi_wctdm_click.diff.txt
This patch avoids the line reversal that happens on the TDM400P 6 seconds
after call is answered.

What I had to do after a fresh install of AsteriskNOW 1.5.0

yum install kernel-devel
cd /usr/src
svn checkout http://svn.digium.com/svn/dahdi/linux/tags/2.1.0.4
dahdi-linux
cd dahdi-linux
wget
"https://issues.asterisk.org/file_download.php?file_id=23002&type=bug"
patch -p0 < dahdi_ohttimer_click.diff.txt
make
make install

shutdown -r now

Debug testing still in patch:
tail -f /var/log/messages
