Parameter Description
is not configured, and 1) and 2) scenarios (described above)
have not provided an isub value, the subaddress remains empty.
Web: Default Cause
Mapping From ISDN to
SIP
[DefaultCauseMapISDN
2IP]
Defines a single default ISDN release cause that is used (in ISDN-to-IP
calls) instead of all received release causes, except when the following
Q.931 cause values are received: Normal Call Clearing (16), User Busy
(17), No User Responding (18), or No Answer from User (19).
The range is any valid Q.931 release cause (0 to 127). The default is 0
(i.e., not configured - static mapping is used).
Release Cause Mapping from ISDN to SIP Table
Web: Release Cause
Mapping Table
EMS: ISDN to SIP
Cause Mapping
[CauseMapISDN2SIP]
This table parameter maps ISDN Q.850 Release Causes to SIP
responses.
The format of this parameter is as follows:
[CauseMapISDN2SIP]
FORMAT CauseMapISDN2SIP_Index =
CauseMapISDN2SIP_IsdnReleaseCause,
CauseMapISDN2SIP_SipResponse;
[\CauseMapISDN2SIP]
Where,
 IsdnReleaseCause = Q.850 Release Cause
 SipResponse = SIP Response
For example:
CauseMapISDN2SIP 0 = 50,480;
CauseMapISDN2SIP 0 = 6,406;
When a Release Cause is received (from the PSTN side), the device
searches this mapping 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: This parameter can appear up to 12 times.
Release Cause Mapping from SIP to ISDN Table
Web: Release Cause
Mapping Table
EMS: SIP to ISDN
Cause Mapping
[CauseMapSIP2ISDN]
This table parameter maps SIP responses to Q.850 Release Causes.
The format of this parameter is as follows:
[CauseMapSIP2ISDN]
FORMAT CauseMapSIP2ISDN_Index =
CauseMapSIP2ISDN_SipResponse,
CauseMapSIP2ISDN_IsdnReleaseCause;
[\CauseMapSIP2ISDN]
Where,
 SipResponse = SIP Response
 IsdnReleaseCause = Q.850 Release Cause
For example:
CauseMapSIP2ISDN 0 = 480,50;
CauseMapSIP2ISDN 0 = 404,3;
When a SIP response is received (from the IP side), the device
searches this mapping table for a match. If the SIP response is found,
the Q.850 Release Cause assigned to it is sent to the PSTN. If no
match is found, the default static mapping is used.
Note: This parameter can appear up to 12 times.
Web/EMS: Enable
Calling Party Category
[EnableCallingPartyCat
egory]
Determines whether Calling Party Category (CPC) is mapped between
SIP and PRI.
 [0] Disable = (Default) Don't relay the CPC between SIP and PRI.
