Amit,
Do you want a soft phone integrated in to the web site or where you have them enter their number and the system calls them and then you. If it is the later I have been using the php script to connect to the AMI.

mc.php

<?php
session_start();
echo '<title>Call Me</title>';
echo '<form action="make_call.php" method="post">
<table width="35%">
<tr><td>Enter your phone number here, country code plus number (e.g. 972732444211 or 17185551212)</td></tr>
<tr><td> <input type="text" name="number" /></td></tr>
<tr><td colspan="1" align="left"><input type="submit" value="Submit" /></td></tr>
</table>
</form>
<img alt="FPP Logo" src="http://www.mydoman.com/support/logo.gif">';
$_SESSION['calling'] = 'yes' ;
?>

and make_call.php

<?php
session_start();
if (!isset($_SESSION['calling'])) {
        echo '<META HTTP-EQUIV="Refresh"CONTENT="0; URL=mc.php">';
                        }
else {

$n2c = $_POST['number'] ;

$_SESSION['calling'] = NULL;

$socket = fsockopen("127.0.0.1","5038", $errno, $errstr);
fputs($socket, "Action: Login\r\n");
fputs($socket, "UserName: username\r\n");
fputs($socket, "Secret: password\r\n");
fputs($socket, "Events: off\r\n\r\n");
# fputs($socket, "\r\n");
# fputs($socket, "\r\n\r\n");
fputs($socket, "Action: Originate\r\n");
fputs($socket, "Channel: SIP/".$n2c."@sip_peer\r\n");
fputs($socket, "Context: some-context\r\n");
fputs($socket, "Exten: s\r\n");
fputs($socket, "Priority: 1\r\n");
fputs($socket, "Callerid: ".$n2c."\r\n");
fputs($socket, "Timeout: 100000\r\n");
#fputs($socket, "Action: ListCommands\r\n\r\n");
fputs($socket, "Action: Logoff\r\n\r\n");
$wrets .= fread($socket, 8192);
fclose($socket);
echo '<title>Call being placed</title>';
echo 'Your call is being placed. Please wait a moment';
}

?>

and from extensions.conf

[some-context]
exten => s,1,Answer
exten => s,2,Dial(SIP/100)

Amit,
I still do not understand the call flow. Do you want a SIP/IAX phone built in to the browser or do you want the user to enter a phone number which the system will then call them on and then connect the call to you ?
