sent only if PI is set to 1 or 8 in the received Proceeding,
Alerting, or Progress PRI messages. See also the
ProgressIndicator2IP parameter, which if set to 1 or 8, the
device behaves as if it received the ISDN messages with
the PI.

CAS: See the ProgressIndicator2IP parameter.

ISDN: Sending a 183 response depends on the ISDN
PI. It is sent only if PI is set to 1 or 8 in the received
Proceeding or Alerting PRI messages. Sending 183
response also depends on the
ReleaseIP2ISDNCallOnProgressWithCause
parameter, which must be set to any value other than
2.

See also the IgnoreAlertAfterEarlyMedia parameter. This
parameter allows, for example, to interwork Alert with PI
to SIP 183 with SDP instead of 180 with SDP.

You can also configure early SIP 183 response
immediately upon the receipt of an INVITE, using the
EnableEarly183 parameter.

The corresponding global parameter is
EnableEarlyMedia.
Defines the progress indicator (PI) sent to the IP.

[-1] Not Configured = (Default)

Digital ISDN: The PI received in ISDN Proceeding,
Progress, and Alerting messages is used, as
described in the options below.

[0] No PI =

Digital: For IP-to-Tel calls, the device sends 180
Ringing response to IP after receiving ISDN Alerting
or (for CAS) after placing a call to PBX/PSTN.

[1] PI = 1:

Digital: For IP-to-Tel calls, if the parameter
EnableEarlyMedia is set to 1, the device sends 180
Ringing with SDP in response to an ISDN Alerting or
it sends a 183 Session 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.

[8] PI = 8: same as PI = 1.
Note: The corresponding global parameter is
ProgressIndicator2IP.
Enables the device to copy the called number, received in
the SIP INVITE message, to the redirect number in the
outgoing Q.931 Setup message, for IP-to-Tel calls. Thus,
even if there is no SIP Diversion or History header in the
incoming INVITE message, the outgoing Q.931 Setup
message will contain a redirect number.

[0] Disable (default).

[1] After Manipulation = Copies the called number after
manipulation. The device first performs IP-to-Tel
destination phone number manipulation, and only then
copies the manipulated called number to the redirect
number sent in the Q.931 Setup message to the Tel.
