12.12.13.3 Number Manipulation Parameters
The number manipulation parameters are described in the table below.
Table 12-65: Number Manipulation Parameters
Parameter Description
Web: Set Redirect number
Screening Indicator to TEL
EMS: Set IP To Tel Redirect
Screening Indicator
[SetIp2TelRedirectScreeningIn
d]
Defines the value of the Redirect Number screening indicator in
ISDN Setup messages.
[-1] Not Configured (default)
[0] User Provided
[1] User Passed
[2] User Failed
[3] 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
