ISDN cause code from the PSTN side, it searches the table for a matching ISDN cause
code. If found, the device sends the corresponding SIP response to the IP. If the ISDN
cause code is not configured in the table, the default, fixed ISDN-to-SIP release reason
mapping is used.
Note: You can change the originally received ISDN cause code to any other ISDN
cause code, using the Release Cause ISDN to ISDN table (see ''Configuring ISDN-to-
ISDN Release Cause Mapping'' on page 526). If the originally received ISDN cause
code appears in both the Release Cause ISDN to ISDN table and the Release Cause
Mapping ISDN to SIP table, the mapping rule in the Release Cause Mapping ISDN to
SIP table is ignored. The device only uses a mapping rule that matches the new ISDN
cause code.
The following procedure describes how to configure ISDN-to-SIP release cause mapping
through the Web interface. You can also configure it through ini file (CauseMapISDN2SIP)
or CLI (configure voip > gateway manipulation cause-map-isdn2sip).

To configure a ISDN-to-SIP release cause mapping rule:
1. Open the Release Cause Mapping from ISDN to SIP table (Setup menu > Signaling
& Media tab > Gateway folder > Manipulation > Release Cause ISDN > SIP).
2. Click New; the following dialog box appears:
Figure 24-7: Release Cause Mapping from ISDN to SIP Table - Add Dialog Box
3. Configure a mapping rule according to the parameters described in the table below.
4. Click Apply.
