route {

if(method == “INVITE”) {
exec_dset(“/usr/local/bin/route.pl $fU $tU”);
sl_send_reply(“302″,”LCR Redirect”);
} else {
route(1);
}

}

In the perl script just write the follow code:

#!/bin/sh
echo sip:+121242415112@howtonix.com

NOTE: To get this to work correctly with Asterisk you need to add “promiscredir=yes” to the general section of your sip.conf

Lighttpd a secure, fast, compliant and very flexible web-server which has been optimized for high-performance environments. It has a very low memory footprint compared to other webservers and takes care of cpu-load.

Lighttpd on FreeBSD:

First update your port tree by typing following commands:

# portsnap fetch
# portsnap update

Install lighttpd web server under FreeBSD

Lighttpd port is located under /usr/ports/www/lighttpd:

# cd /usr/ports/www/lighttpd

Install lighttpd:

# make
# make install
# make clean

Start Lighttpd Server Under FreeBSD

To start Lighttpd server, enter:

# /usr/local/etc/rc.d/lighttpd start

Verify that lighttpd is running:

# netstat -nat

Auto start lighttpd service

You need to enable both services. Open /etc/rc.conf:

# vi /etc/rc.conf

Append following two lines:

lighttpd_enable="YES"

Add the following code in mmp file:
OPTION GCCE -O2 -fno-unit-at-a-time

First you have to download & install ptlib:

In your home, create a directory e.g. h323
mkdir -p ~/h323
cd ~/h323
wget http://www.h323plus.org/source/download/ptlib-2.4.5.tar.bz2
bunzip2 ptlib-2.4.5.tar.bz2
tar -xvf ptlib-2.4.5.tar.bz2
mv ptlib-2.4.5 ptlib-trunk
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export LD_LIBRARY_PATH=/usr/local/lib
cd ptlib-trunk
./configure
make
sudo make install
cd ..

Now, install h323plus

cd ~/h323

http://www.h323plus.org/source/download/h323plus-v1_21_0.tar.gz

export PTLIBDIR=~/h323/ptlib-trunk

tar -xzvf h323plus-v1_21_0.tar.gz
cd h323plus
./configure
make
make install

Now install mod_h323 on Freeswitch.

assuming you have FS source in your home
cd ~/freeswitch-trunk

make mod_h323-clean
make mod_h323
sudo make mod_h323-install

Now configure h323.conf.xml. It is similiar like mod_opal.

<configuration name=”h323.conf” description=”H323 Endpoints”>
  <settings>
    <param name=”trace-level” value=”4″/>
    <param name=”context” value=”public”/>
    <param name=”dialplan” value=”XML”/>
    <param name=”codec-prefs” value=”PCMU,PCMU,G729,GSM”/>
  </settings>
  <listeners>
    <listener name=”myH323_listener”>
      <param name=”h323-ip” value=”$${local_ip_v4}”/>
      <param name=”h323-port” value=”1720″/>
    </listener>
  </listeners>
</configuration>

 

   

You can create tar.gz file with the following command.DO NOT ENTER / after the directory name.

tar -cvzf  test.tar.gz test

In the var_config.cfg file, you can now turn on a feature to block incoming
H323 calls. Set the following two lines:

H323Q931PortFlag 1
H323Q931PortNum 1788 or some other number for listening port (other than 0)”

Save as var_config.cfg and upload via FTP.
