Pluginbox is a special Kannel box that sits between bearerbox and smsbox and allows plugins to execute and manipulate messages in both directions.
Pluginbox behaves similar to other Kannel boxes and share a compatible configuration file format and command line options.
Before you can compile pluginbox and plugins you need a Kannel version installed on your OS with the -fPIC flag set.
To do this, you can just follow the commands below:
svn checkout https://svn.kannel.org/gateway/trunk kannel-svn
cd kannel-svn
CFLAGS="-fPIC" ./configure
make
sudo make install
Please read the INSTALL file for further instructions. If in a hurry, the quick explanation is:
./bootstrap
./configure
make
And finally, as root:
make install
For example purposes I have included an HTTP plugin which can intercept all messages to and from Kannel and forward them to an HTTP URL. In the headers will be included all the parameters of the message, which can then be changed by the HTTP server or simply reject the message.
Please see contrib/plugin-http/pluginbox_http.conf as well as example/pluginbox.conf.example for an example of how to configure.
There is also a PHP script example showing how to reject messages as well as modify parameters of the message structures in contrib/plugin-http/http-processor.php
You need to have a compiled version of Kannel available in order to compile pluginbox.
The Userguide has also valuable information about the install and configuration steps.
The best to ask for help is on Kannel's mailing lists.
