I ever hear about Kannel that could be used as SMS gateway, but i am not sure whether it need or not other SMS center instrument. (www[dot]kannel[dot]org/status.shtml[/url]. To send SMS / text message basically we need SMPP sever on our vps.
I am looking forward from you guys, if you succeeded installing your sms gateway, pls let's us know
Hope, KH will allow us to install SMS gateway on it.
