Valid Range and Description
CauseMapISDN2SIP_ID
[Release Cause Mapping
from ISDN to SIP]
Defines a flexible mapping of Q.850 Release Causes and SIP Responses.
CauseMapISDN2SIP_<ID> = <Q.850 Release Cause>,<SIP Response>
When a Release Cause is received (from the PSTN side), the gateway
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.
For example:
CauseMapISDN2SIP=6,406
This parameter can appear up to 12 times.
RemoveCLIWhenRestric
ted
[Remove CLI when
Restricted]
Determines (for IP to Tel calls) whether the Calling Number IE and Calling
Name IE are removed from the outgoing ISDN Setup message if the
presentation is set to Restricted.
0 = IE aren’t removed (default).
1 = IE are removed.
ScreeningInd2ISDN
[Send Screening Indicator

Overwrites the screening indicator of the calling number for IP
Æ
Tel (ISDN)
calls.
-1 = Not Configured (interworking from IP to ISDN) (default).
0 = User provided, not screened.
1 = User provided, verified and passed.
2 = User provided, verified and failed.
3 = Network provided.
ProgressIndicator2ISDN
_ID
[Progress Indicator to
ISDN]
ID = Trunk number (0-7).
0, 1 or 8
-1 = Not configured (default).
If set to ‘0’ PI is not sent to ISDN
If set to ‘1’ or ‘8’ the PI value is sent to PSTN in Q.931/Proceeding and Alerting
messages.
If not configured, the PI in ISDN messages is set according to the ‘Play
Ringback to Tel’ parameter.
Usually if PI = 1 or 8, the PSTN/PBX cuts through the audio channel without
playing local Ringback tone, enabling the originating party to hear remote Call
Progress Tones or network announcements
ProgressIndicator2IP
[Progress Indicator to IP]
-1 = (Not configured) for ISDN spans, the progress indicator (PI) that is
received in ISDN Proceeding, Progress and Alert messages is used as
described in the options below (default).

Tel call, the gateway sends ‘180 Ringing’ SIP response to
IP after receiving ISDN Alert or (for CAS) after placing a call to PBX/PSTN.
8, 1 = For IP
Æ
Tel call, if ‘EnableEarlyMedia=1’, the gateway sends ‘180
Ringing’ with SDP in response to an ISDN alert, or it sends a ‘183 session in
progress’ message with SDP in response to only the first received ISDN
Proceeding or Progress message, after a call is placed to PBX/PSTN over the
trunk. This is used to cut through voice path before the remote party answers
the call, enabling the originating party to listen to network Call Progress Tones
(such as Ringback tone or other network announcements).
