This page provides instruction for how to using the BT SDK in PHP with XXAMP
1 .. Install XAMPP (http://www.apachefriends.org/en/xampp.html)
This is not required but this particular apache configuration has been tested.
2 .. Register for an account at http://sdk.bt.com/
3 .. Download the PHP source files: Downloads > PHP
4 .. Unzip the directory into your htdocs folder. If you installed XAMPP to the default location the htdocs folder will be in : C:\xampp\htdocs
Unzip the files to a folder of your choosing. With the default install this can be found at:

7 .. Ensure that the application name is the same as the one specified when generating your certificate.
8 .. Open the folder C:\xampp\htdocs\phpWeb21C\examples\cmds
You should now be able to configure and run these files.
9 .. Running the code. If you have used the default installation settings go to and edit the file:
Change the variables for :
$calling = "tel:+44791";
$called = "tel:+44791";
To the numbers you wish to ring when the page is run.
When you now open the file in a browser the phones should start ringing. http://127.0.0.1/phpWeb21C/examples/cmds/makeCall.php
