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.

Message
EMS: Set PI For Disconnect
Msg
CLI: pi-in-rx-disc-msg

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.

number, where 0 is Trunk 1.
EMS: Connect On Progress Ind
[ConnectOnProgressInd]

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.

Progress message is received.
