SIP User's Manual A. Configuration Parameters Reference
Parameter Description
Web: Send Screening Indicator to
ISDN
EMS: Screening Indicator To ISDN
[ScreeningInd2ISDN]
Overrides the screening indicator of the calling party's number
for IP-to-Tel ISDN calls.
 [-1] Not Configured = Not configured (interworking from IP to
ISDN) (default).
 [0] User Provided = user provided, not screened.
 [1] User Passed = user provided, verified and passed.
 [2] User Failed = user provided, verified and failed.
 [3] Network Provided = network provided
Note: This parameter is applicable only to digital PSTN
interfaces (ISDN).
Web: Copy Destination Number to
Redirect Number
EMS: Copy Dest to Redirect
Number
[CopyDest2RedirectNumber]
Determines whether the device copies the received ISDN
(digital interfaces) called number to the outgoing SIP Diversion
header for Tel-to-IP calls
(even if a Redirecting Number IE is not
received in the ISDN Setup message, for digital interfaces).
Therefore, the called number is used as a redirect number. Call
redirection information is typically used for Unified Messaging
and voice mail services to identify the recipient of a message.
 [0] Don't copy = Disable (default).
 [1] Copy after phone number manipulation = Copies the
called number after manipulation. The device first performs
Tel-to-IP destination phone number manipulation (i.e., on the
SIP To header), and only then copies the manipulated called
number to the SIP Diversion header for the Tel-to-IP call.
Therefore, with this option, the called and redirect numbers
are identical.
 [2] Copy before phone number manipulation = Copies the
called number before manipulation. The device first copies
the original called number to the SIP Diversion header, and
then performs Tel-to-IP destination phone number
manipulation. Therefore, this allows you to have different
numbers for the called (i.e., SIP To header) and redirect (i.e.,
SIP Diversion header) numbers.
Notes:
 For digital interfaces: If the incoming ISDN-to-IP call includes
a Redirect Number, this number is overridden by the new
called number if this parameter is set to [1] or [2].
 When configured in an IP Profile, this parameter can also be
used for IP-to-
Tel calls. The device can overwrite the redirect
number with the destination number from the received SIP
INVITE message in the outgoing ISDN call. This is achieved
by assigning an IP Profile (IPProfile parameter) defined with
the CopyDest2RedirectNumber parameter set to 1, to the IP-
to-Tel Routing table (PSTNPrefix parameter). 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.
 This parameter can also be configured per IP Profile (using
the IPProfile parameter).
[ReplaceCallingWithRedirectNu
mber]
Enables the replacement of the calling number with the redirect
number for ISDN-to-IP calls.
 [0] = Disable (default).

[1] = The calling name is removed and left blank. The
