code is not configured in the table, the originally received ISDN cause code is used. If the
new ISDN cause code also appears in the Release Cause Mapping ISDN to SIP table (see
'Configuring ISDN-to-SIP Release Cause Mapping' on page 576), the device maps it to the
corresponding SIP response code, which it sends to the IP side.
Note: If the originally received ISDN cause code is configured in both the Release
Cause ISDN to ISDN table and the Release Cause Mapping ISDN to SIP table, the
mapping rule with the originally received code in the Release Cause Mapping ISDN to
SIP table is ignored; the device uses only the mapping rule in the Release Cause
Mapping ISDN to SIP table that matches the new ISDN cause code. For example, if
you configure a mapping rule in the Release Cause ISDN to ISDN table to change a
received 127 code to 16, the device searches for a rule in the Release Cause
Mapping ISDN to SIP table for an ISDN code of 16 (ignoring any entry with code
127).
The following procedure describes how to configure ISDN-to-ISDN release cause mapping
through the Web interface. You can also configure it through ini file (CauseMapIsdn2Isdn)
or CLI (configure voip > gateway manipulation cause-map-isdn2isdn).
 To configure a ISDN-to-ISDN release cause mapping rule:
1. Open the Release Cause Mapping from ISDN to ISDN table (Setup menu >
Signaling & Media tab > Gateway folder > Manipulation > Release Cause ISDN >
ISDN).
2. Click New; the following dialog box appears:

3. Configure a mapping rule according to the parameters described in the table below.
4. Click Apply.
Table 25-12: Release Cause Mapping ISDN to ISDN Table Parameter Descriptions
Parameter Description
Index
[CauseMapIsdn2Isdn_Index]
Defines an index number for the new table row.
Note: Each row must be configured with a unique
index.
Orig. Q.850 Causes
q850-causes
[CauseMapIsdn2Isdn_OrigIsdnReleaseCause]
Defines the originally received ISDN Q.850 cause
code. For example, you can enter "127" (without
apostrophes) to represent cause code 127
Interworking, Unspecified.
The valid value (cause code) is 1 to 127.
