The screenshot of the SIP-T46G IP phone user interface for reference is shown as below:

The phone can request an XML object via HTTP GET, or an object can be pushed to the

phone via a POST. The phone parses this object immediately upon receipt and

displays the information on the screen.

The HTTP POST packet must contain an “xml=” line in the message body. XML data is

located after the equals sign in the message. HTML forms that post objects to the

phone must use a field named “xml” to send data. Any applications that construct

HTTP packets on the fly must also specify this line.

To accept a pushed message, the “PushXML_ServerIP” parameter on the phone must

be configured as the IP address of the push XML server. For more information, refer to

Configuring the Push XML Server Address.

Description of the object oriented php class:

<?php

function push2phone($server,$phone,$data)

{

$xml = "xml=".$data;

$post = "POST / HTTP/1.1\r\n";

$post .= "Host: $phone\r\n";

$post .= "Referer: $server\r\n";

$post .= "Connection: Keep-Alive\r\n";

$post .= "Content-Type: text/xml\r\n";

$post .= "Content-Length: ".strlen($xml)."\r\n\r\n";

$fp = @fsockopen ( $phone, 80, $errno, $errstr, 5);
