Configuring Release Cause Mapping

The Release Cause Mapping table allows you to map up to 12 different ISDN ITU-T Q.850
cause codes, which indicate reasons for ISDN call failure, to SIP response codes, and vice
versa. This allows you to override the default release cause mappings between ISDN and
SIP, as described in 'Fixed Mapping of ISDN Release Reason to SIP Response' on page
351 and 'Fixed Mapping of SIP Response to ISDN Release Reason' on page 349.

For Tel-to-IP calls, you can also map the less commonly used SIP
responses to a single default ISDN Release Cause, using the
DefaultCauseMapISDN2IP parameter. This parameter defines a default
ISDN Cause that is always used except when the following Release
Causes are received: Normal Call Clearing (16), User Busy (17), No
User Responding (18) or No Answer from User (19).
•
The release cause mapping tables can also be configured using the ini
file:
1) Release Cause Mapping from ISDN to SIP table:
CauseMapISDN2SIP (ini).
2) Release Cause Mapping from SIP to ISDN
table:CauseMapSIP2ISDN (ini).
