	// ABSTRACT:  This function is called by the Retry thread if this call
	//            is due to report an unsolicited status to the gatekeeper.
	//            It is also called in response to a received IRQ.  In the
	//            case of an IRQ, each active call should chain call the 
	//            next active call.  This allows construction of a link
	//            list of conference information that is then passed to the
	//            CRegistration::SendInfoRequestResponse function for
	//            encapsulation into the IRR message.
	//
	//			  The fThisCallOnly flag determines whether or not to walk the
	//			  chain of calls in generating the response message.
	//
	//			  If fThisCallOnly == TRUE, the chain will not be walked, and
	//			  this routine will call the CRegistration::SendInfoRequestResponse().
