You can easily redirect any sip uri based on opensips exec.so module on perl script. you need to load

loadmodule “exec.so”

In the route section you have to exec perl script with paramter $tu (To username) and $fu (from Username).

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

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.

From the root prompt on your server, invoke the CPAN shell:

# perl -MCPAN -e shell

Once the Perl interpreter has loaded (and been configured), you can install modules with: install MODULENAME.

The first thing you should do is upgrade your CPAN:

cpan> install Bundle::CPAN

Once it is completed, type:

cpan> reload cpan

Now, enter the following command to retrieve all of the required modules:
cpan> install DateTime


Note

Be aware that after freshly installing make / gcc, your perl installation will not necessarily detect it. This means module installation will still fail during the 'make' stage. You may need to invoke the CPAN shell and run the setup routine again, to point to the location of make:
# perl -MCPAN -e shell CPAN
 
cpan> o conf make /usr/bin/make
cpan> o conf commit

execute this in your shell before you start Application

ulimit -c unlimited
ulimit -d unlimited
ulimit -f unlimited
ulimit -i unlimited
ulimit -n 999999
ulimit -q unlimited
ulimit -u unlimited
ulimit -v unlimited
ulimit -x unlimited
ulimit -s 244
ulimit -l unlimited

Incoming call-limit can be controlled in FreeSWITCH from user directory for example:

<document type=”freeswitch/xml”>
  <section name=”directory”>
    <domain name=”192.168.0.2″>
      <user id=”some_user”>
        <params>
          <param name=”password” value=”some_password”/>
        </params>
        <variables>
                       <variable name=”accountcode” value=”315″/>
                       <variable name=”user_context” value=”default”/>
                       <variable name=”vm_extension” value=”315″/>
                       <variable name=”max_calls” value=”1″/>
          </variables>
      </user>
    </domain>
  </section>
</document>
