release codes. When a Release Cause is received from the PSTN, the device
searches this table for a match. If the Q.850 Release Cause is found, the SIP
response assigned to it is sent to the IP side. If no match is found, the default static
mapping is used.
Note: 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 following procedure describes how to configure ISDN-SIP release cause mapping in
the Web interface. You can also configure this mapping using the following management
platforms:

Release Cause Mapping from ISDN to SIP table: ini file parameter,
CauseMapISDN2SIP or CLI command, configure voip > gw manipulations cause-map-
isdn2sip

Release Cause Mapping from SIP to ISDN table:ini file parameter,
CauseMapSIP2ISDN or CLI command, configure voip > gw manipulations cause-map-
sip2isdn

To configure an ISDN-SIP release cause mapping rule:
1. Open the required release cause mapping table (Configuration tab > VoIP menu >
GW and IP to IP > Manipulations > Release Cause SIP > ISDN or Release Cause
ISDN > SIP).
2. Click Add; the following dialog box appears:
3. Configure a mapping rule according to the parameters described in the table below.
4. Click Submit, and then save ("burn") your settings to flash memory.
