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).
 To configure a ISDN-to-ISDN release cause mapping rule:
1. Open the Release Cause Mapping from ISDN to ISDN table (Configuration tab >
VoIP menu > Gateway > Manipulations > Release Cause ISDN > ISDN).
2. Click Add; the following dialog box appears:
Figure 24-8: Release Cause ISDN to ISDN Table - Add Row Dialog Box
3. Configure a mapping rule according to the parameters described in the table below.
4. Click Add.
