 /**
+ * This is a convenient function which wraps #pjsip_get_response_addr() and
+ * #pjsip_endpt_send_response() in a single function.
+ *
+ * @param endpt     The endpoint instance.
+ * @param rdata     The original request to be responded.
+ * @param tdata     The response message to be sent.
+ * @param token     Token to be passed back when the callback is called.
+ * @param cb        Optional callback to notify the transmission status
+ *                  to application, and to inform whether next address or
+ *                  transport will be tried.
+ * 
+ * @return          PJ_SUCCESS if response has been successfully created and
+ *                  sent to transport layer, or a non-zero error code. 
+ *                  However, even when it returns PJ_SUCCESS, there is no 
+ *                  guarantee that the response has been successfully sent.
