Cause Code Mapping
If Diva SIPcontrol uses Microsoft
®
Office Communications Server 2007 or Lync Server 2010
as a SIP peer, the cause/response code tables are used as specified by Microsoft. See
Default Cause Code Mapping for Microsoft® Office Communications Server 2007 and Lync
Server 2010 Peers for a detailed list of cause/response codes.
If Diva SIPcontrol does not use Microsoft
®
Office Communications Server 2007 or Lync
Server 2010, the default cause/response code mapping is used. See Default Cause Code
Mapping for a detailed list of cause/response codes.
Default Cause Code Mapping
Diva SIPcontrol includes a default cause/response code mapping table that includes the
most common cause codes according to RFC 3398 and RFC 4497. If you need to define a
cause code mapping other than in the table, you can configure it in the Cause Code Maps
section.
For ISDN to SIP code mappings, see ISDN Cause Code to SIP Response Code.
For SIP to ISDN code mappings, see SIP Response Code to ISDN Cause Code.
