Configuring Release Cause Mapping

The release cause mapping tables let you configure rules to map up to 12 different ISDN
ITU-T Q.850 release cause codes (call failure) to SIP response codes, and vice versa.
These tables allow you to override the default ISDN-SIP release cause mappings,
described in ''Fixed Mapping of ISDN Release Reason to SIP Response'' on page
''Fixed Mapping of SIP Response to ISDN Release Reason'' on page 377.
The release cause mapping tables include:

Release Cause Mapping from SIP to ISDN table: Maps SIP release codes to ISDN
cause codes. When a SIP response is received from the IP side, the device searches
this table for a match. If the SIP response is found, the Q.850 Release Cause
assigned to it is sent to the PSTN. If no match is found, the default static mapping is
used.

Release Cause Mapping from ISDN to SIP table: Maps ISDN cause codes to SIP
Version 6.8
Defines an index number for the new table record.
Determines whether the received SIP 'phone-context' parameter is
added as a prefix to the outgoing ISDN Setup message (for digital
interfaces) with called and calling numbers.
