Mediant 500L MSBR
Parameter Description
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.
 Analog: To send a 183 response, you must also set the
ProgressIndicator2IP parameter to 1. If set to 0, a 180
Ringing response is sent.
 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)

Analog: Default values are used (1 for FXO interfaces
and 0 for FXS interfaces).

Digital ISDN: The PI received in ISDN Proceeding,
Progress, and Alerting messages is used, as
described in the options below.
 [0] No PI =

Analog: For IP-to-Tel calls, the device sends a 180
Ringing response to IP after placing a call to a phone
(FXS) or PBX (FXO).

Digital: For IP-to-Tel calls, the device sends 180
Ringing response to the IP after receiving an ISDN
Alerting or (for CAS) after placing a call to the
PBX/PSTN.
 [1] PI = 1:

Analog: For IP-to-Tel calls, if the EnableEarlyMedia
parameter is set to 1, the device sends a 183
Session Progress message with SDP immediately
after a call is placed to a phone/PBX. This is used to
cut-through the voice path before the remote party
answers the call. This allows the originating party to
listen to network call progress tones such as ringback
tone or other network announcements.

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
