/* 
 * The SipServer object serves as a very simple SIP server or a front-end
 * to the UAServer (user agent server) by listening for incoming calls 
 * and starts a UAServer thread to handle the call.  It is implemented 
 * as a background thread within Simphony, therefore should be running
 * all the time.
