Version 6.8 313 Mediant 500 E-SBC
Parameter Description
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.
Web: Progress Indicator to IP
CLI: prog-ind-to-ip
[IpProfile_ProgressIndicator2IP] 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.
Web: Copy Destination Number to
Redirect Number
CLI: copy-dst-to-redirect-number
[IpProfile_CopyDest2RedirectNumber] 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.
