The SIPResponseMetaDataTable contains a list of SIP response codes and the classification and definition of each of those codes. These codes are generated in response to events affecting SIP devices and SIP communication sessions; for example, the response code 403 is generated when a SIP device makes a request, but the server declines to honor that request.

This table was introduced in Microsoft Lync Server 2013.
