ini File Field Name
Web Parameter Name
Valid Range and Description
ScreeningInd2ISDN
[Send Screening Indicator
to ISDN]
Overwrites the screening indicator of the calling number for IPÆTel (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).
0 = (No PI) For IPÆTel 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 IPÆTel 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).
PIForDisconnectMsg_ID
[Set PI in Rx Disconnect
Message]
ID = Trunk number (0-7).
Defines the gateway’s behavior when a Disconnect message is received from the
ISDN before a Connect message was received.
-1 (Not configured) = Sends a 183 message according to the received PI in the
ISDN Disconnect message. If PI = 1 or 8, the gateway sends a 183 response,
enabling the PSTN to play a voice announcement to the IP side. If there isn’t a PI
in the Disconnect message, the call is released (default).
0 = Do not send a 183 message to IP. The call is released.
1, 8 = Sends 183 message to IP.
ConnectOnProgressInd
0 = Connect message isn’t sent after 183 Session Progress is received (default).
1 = Connect message is sent after 183 Session Progress is received.
This feature enables the play of announcements from IP to PSTN without the
need to answer the TelÆIP call. It can be used with PSTN networks that don’t
support the opening of a TDM channel before an ISDN Connect message is
received.
SIP183Behaviour
[183 Message Behavior]
Defines the ISDN message that is sent when 183 Session Progress message is
received for IPÆTel calls.
0 = Progress message (default).
1 = Alert message.
When set to 1, the gateway sends an Alert message (after the receipt of a 183
response) instead of an ISDN Progress message.
LocalISDNRBSource_ID
[Local ISDN Ringback
Tone Source]
ID = Trunk number (0-7).
Determines whether Ringback tone is played to the ISDN by the PBX / PSTN or
by the gateway.
0 = PBX / PSTN (default).
1 = Gateway.
This parameter is applicable to ISDN protocols. It is used simultaneously with the
parameter ’PlayRBTone2Trunk’.
