Parameter Description
number, where 0 is Trunk 1.
Web/EMS: Progress Indicator
to ISDN
CLI: pi-to-isdn
[ProgressIndicator2ISDN_x]
Determines the Progress Indicator (PI) to ISDN per trunk.

[-1] Not Configured = (Default) The PI in ISDN messages is set
according to the parameter PlayRBTone2Tel.

[0] No PI = PI is not sent to ISDN.

[1] PI = 1; [8] PI = 8: The PI value is sent to PSTN in
Q.931/Proceeding and Alerting messages. Typically, 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.
Note: The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
Web: Set PI in Rx Disconnect
Message
EMS: Set PI For Disconnect
Msg
CLI: pi-in-rx-disc-msg
[PIForDisconnectMsg_x]
Defines the device's behavior per trunk when a Disconnect
message is received from the ISDN before a Connect message is
received.

[-1] Not Configured = (Default) Sends a 183 SIP response
according to the received progress indicator (PI) in the ISDN
Disconnect message. If PI = 1 or 8, the device 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.

[0] No PI = Doesn't send a 183 response to IP. The call is
released.

[1] PI = 1; [8] PI = 8: Sends a 183 response to IP.
Note: The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
EMS: Connect On Progress Ind
[ConnectOnProgressInd]
Enables the play of announcements from IP to PSTN without the
need to answer the Tel-to-IP 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.

[0] = (Default) Connect message isn't sent after SIP 183 Session
Progress message is received.

[1] = Connect message is sent after SIP 183 Session Progress
message is received.

EMS: Local ISDN RB Source
CLI: local-isdn-rbt-src
[LocalISDNRBSource_x]
Determines whether the ringback tone is played to the ISDN by the
PBX/PSTN or by the device, per trunk.

[0] PBX = (Default) PBX/PSTN plays the ringback tone.

[1] Gateway = The device plays the ringback tone.


This parameter is used together with the PlayRBTone2Trunk
parameter.

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.
Web/EMS: PSTN Alert Timeout
CLI: pstn-alrt-timeout
[TrunkPSTNAlertTimeout_x]
Defines the Alert Timeout (ISDN T301 timer) in seconds for
outgoing calls to PSTN, per trunk. This timer is used between the
time that an ISDN Setup message is sent to the Tel side (IP-to-Tel
call establishment) and a Connect message is received. If Alerting
is received, the timer is restarted.
The range is 1 to 600. The default is 180.
