Steps for setting up the SDK
For a number of BT Osmosoft demos we have demonstrated how to make phone calls from within a TiddlyWiki, I thought i would provide a post which explains exactly what we did in order to set up the PHP side of these demos.
The demo I am refering to can be found at the following URL's:
Step 1 You need a web server running :
OpenSSL and SOAP PHP extensions
Step 2 - Register for an account at http://sdk.bt.com/
Step 3 - Download the PHP source files: Downloads > PHP
Step 4 - Upload the files to a folder on your web server.
Step 5 - Registering your applications...
Note : Before you can use the SDK you will need to register an application (One registration covers all of your programs)
You can register application at the URL below:
In order to run the certificate generation tool you may need the latest version of “Java Runtime Environment (JRE)” from http://java.sun.com/javase/downloads/index.jsp (you will receive an error when attempting to run the tool if you require this upgrade.)
When you use the tool 3 files will be generated on your desktop. (I called my app Umbrella)
_APPLICATIONNAME\_Sandbox\_PrivateKey.pem_ _APPLICATIONNAME\_Sandbox\_PublicKey.pem_ _APPLICAIONNAME\_Sandbox\_SignedCert.pem_
Two of those files :
Should then be place in a folder called keys (which you may need to create).
Step 6 - Open the common.php file which can be found in the folder:
Step 7 - Ensure that the application name is the same as the one specified when generating your certificate**.**
Step 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″;
You will need to modify these two lines so that they can receive an input from the URL, I would suggest changing these to:
$calling ='tel:'.$\_REQUEST\['callingParty'\]; $called = 'tel:'.$\_REQUEST\['calledParty'\] ;
You will need to ensure that the variable names are the same as the variables sent my TiddlyWiki.
Let me know if you have any problems.
