18.3.7 Configuring Release Cause Mapping
The Release Cause Mapping page consists of two groups that allow the device to map up
to 12 different SIP Response Codes to ITU-T Q.850 Release Cause Codes and vice versa,
thereby overriding the hard-coded mapping mechanism (described in 'Release Reason
Mapping' on page 242).
Note: You can also configure SIP Responses-Q.850 Release Causes mapping
using the ini
file table parameters CauseMapISDN2SIP and
CauseMapSIP2ISDN (see 'ISDN and CAS Interworking-Related Parameters'
on page 698).
 To configure Release Cause Mapping:
1. Open the Release Cause Mapping page (Configuration tab > VoIP menu > GW and
IP to IP submenu > Manipulations submenu > Release Cause Mapping).
