 Specification
----------------------------------------------------------------------------------
RCCI based on PHP includes the following files: 

	1. Page file "rcci.php".
	2. Page file "rcci_updateconfig.php".
	3. PHP class file "XMLCalls_inc.php".
	3. CSS file "styles.css".

The class constructor should initialize objects with the connection and authentication parameters as shown below:

	$net = new XMLCalls ($ip_addr, $port, $user_name, $password)

XMLCalls_inc.php contains the class XMLCalls that has the following interface functions:

Authenticate() 
	authenticates the user on the Quadro with the "$user_name" and "$password" specified when creating the object.

Join($from, $to, $from2, $to2, $play_filename) 
	creates 2 calls, plays a message to the second called party, then joins the calls.
What happens if executed: 
	the party "$to" rings, indicating the "$from" as a caller. 
	Once "$to" answers the call, "$to2" rings, indicating the "$from2" as a caller. 
	The party "$to" hears silence. Once "$to2" answers the call, the voice message, specified as $play_filename", is played. 
	When the playback is complete, the parties "$to" and "$to2" are connected, and can talk to each other.

Transfer($from, $to, $transfer_to) 
	creates a call from the party "$from" to "$to", then transfers it to the party "$transfer_to".
What happens if executed: 
	the party "$to" rings, indicating the "$from" as a caller. 
	Once "$to" answers the call, the party "$transfer_to" will ring. 
	While the call is ringing at the party "$transfer_to"�s phone, "$to" listens ring-back tone. 
	If the party "$transfer_to" answers the call, a two-way communication is established between "$to" and "$transfer_to".

UpdateConfig($filePath) 
	upload legible configuration file specified by "$filepath" to Quadro.

There are some low-level interface functions, the main of which is the following:

Call($from, $to) 
	creates a simple call. After calling this function, the "$to" party will ring, indicating the "$from" as a caller. 
	After "$to" answers the call, they hear silence. 
	The call created by this function, should be handled further, using methods shown in the example.
