I have 1 more question. I want to reply automatically whenever the gateway receives a SMS. how to do that?
I mean is there a way using PHP?? i'm using PHP and mysql. When the gateway get a SMS in a specific format, i want to filter out specific words from the SMS and search the database, then send the result to the user.

Do i have to write all code for this in shell script? (Inside the eventhandler?) or any other method like in PHP or something like that?

Please guide me..

Thank you.

Eventhandler can be used to create an automatic reply. In many cases it's a shell script, but it depends on the user. Any language can be used to create an eventhandler, for example PHP. From the shell script you can also call a program written with PHP.

This forum contains some sample code but these are shell scripts. Use the search for eventhandler to find those posts, like SMS Forwarding and Configuring filter.

Thank you very much for the reply.
I'll try that.
