Cisco 79XX XML Push
If you want to Push an XML Object to a Cisco IP Phone, it first tries to authenticate your request against a Call Manager. If you don't have a Call Manager (e.g. you're using Asterisk), then you can use "<authenticationURL></authenticationURL>" in the SEP<MAC>.cnf.xml. The phone can then be directed to any web server which handles the authentication.
Data transferred:
1) The Push is done by posting a "CiscoIPPhoneExecute" with the URL of the Object you want to be loaded. The POSTing has to be directed to the phone at the URL "/CGI/Execute" and must use HTTP Basic Authentication.
2) The phone POSTs 'UserID', 'Password' and 'devicename'
3) The server answers 'ERROR', 'UN-AUTHORIZED' or 'AUTHORIZED' (ensure no headers sent and no extra characters. The phone will respond with a 'CiscoIPPhoneError Number="4"' if it receives anything extra.)
Now it's up to you, what your script answers according to UserID andPassword.
A simple authentication script, always allowing access, would be:
<?
php echo "AUTHORIZED";
?>
(NB This doesn't check UserID and Password) Also make sure that there are no extra characters, such as spaces, outside the <?php....?>.
An example to send an Execute Object to the phone, containing the URL you want to be pulled:
<?php
## This is an example of CiscoIPPhoneExecute as seen in the SDK
## Usage: Simply include in your php program and call the funtion
# using the parameters:
# $ip = IP of phone we're pushing to
# $uri = the URL or URI we want the phoneto execute
# $uid = the user id to authenticateagainst to the phone
# $pwd = the password to authenticate
