Opensmppbox is also a box similar to sqlbox which runs on top of kannel.
However this is a special type of box that will listen to incoming SMPP Connections to allow messages to be sent to and from SMPP Clients allowing you to act as an SMPP Provider.
Go to the directory where is your gateway.
Then just run the command as given below:-
# make install
Congrats opensmppbox has been installed.
