The Web interface contains two tables that define mapping between ISDN Cause Codes and SIP
Responses.
• ISDN Cause Codes to SIP Response
• SIP Responses to ISDN Cause Codes
3.13.1.1 ISDN Cause Codes to SIP Response

takes effect under the following scenarios: on progress messages, disconnect received, disconnect
indicator, and when the set facility request fails.
