Q:

Voice recording : Using Red 5 server with PHP /Java

I have requirement where I have to use RED 5 media server for voice recording which going to embed in web page.  So I have installed the RED 5 server which is up and running. 
Now I not getting any clue how should I start coding in php (since site is designed in php) and design a voice-recording application. 

A:

I had experience in the past with RED5 and some application as video or sound recorder. 
You need to use Flash or Flex with ActionScript to connect to RED5 and then record the stream
There are many examples in Red5 in the webapps folder, try to download some .FLA and look inside the code. 
The oflaDemo is a good start for understand how does it work.  There are also example as SimpleRecorder or MessageRecorder (up the version you'd installed)
Here a simple example about ActionScript
// create the connection
var nc:NetConnection = new NetConnection();
nc.connect("rtmp://localhost/myApp");

// create the stream
var ns:NetStream = new NetStream(nc);
ns.publish("myStreamName", "record");

The result will be an FLV file named myStreamName.flv located in your webapp’s streams directory. 
Once you develop your Flash application you can embed this .SWF in your webpage with PHP
On internet there are a lot of examples and open-source as Video or Sound recorder as:

Hope this help you to start
