How can i use multiple click2call buttons?

Here is click to call documentation:
http://docs.flashphoner.com/display/WCS/Click2call
http://docs.flashphoner.com/display/WCS/Click2call+quick+start
http://docs.flashphoner.com/display/WCS/Autologin

As described in the docs, our click2call example uses account.xml and callee.xml which located at /usr/local/FlashphonerWebCallServer/conf
However, you can use your own dynamic php scripts.

For example:
http://mydomain.com/account.php?token=12345
http://mydomain.com/callee.php?token=12345

So you will be able to use multiple click2call connections and directions. You can handle it by your PHP scripts.
