Parameter Description
Number
EMS: Add NPI And TON As Prefix
To Calling Number
[AddNPIandTON2CallingNumber
]
Type of Numbering (TON) are added to the Calling Number for
Tel-to-IP calls.
 [0] No = Do not change the Calling Number (default).
 [1] Yes = Add NPI and TON to the Calling Number ISDN Tel-
to-IP call.
For example: After receiving a Calling Number of 555, NPI of 1,
and TON of 3, the modified number becomes 13555. This
number can later be used for manipulation and routing.
Web: Add NPI and TON to Called
Number
EMS: Add NPI And TON As Prefix
To Called Number
[AddNPIandTON2CalledNumber]
Determines whether NPI and TON are added to the Called
Number for Tel-to-IP calls.
 [0] No = Do not change the Called Number (default).
 [1] Yes = Add NPI and TON to the Called Number of ISDN
Tel-to-IP call.
For example: After receiving a Called Number of 555, NPI of 1
and TON of 3, the modified number becomes 13555. This
number can later be used for manipulation and routing.
Web: IP to Tel Remove Routing
Table Prefix
EMS: Remove Prefix
[RemovePrefix]
Determines whether the device removes the prefix from the
destination number for IP-to-Tel calls.
 [0] No = Don't remove prefix (default)
 [1] Yes = Remove the prefix (defined in the Inbound IP
Routing Table - see 'Configuring Inbound IP Routing Table'
on page 279) from a telephone number for an IP-to-Tel call
before forwarding it to Tel.
For example: To route an incoming IP-to-Tel call with
destination number 21100, the Inbound IP Routing Table is
scanned for a matching prefix. If such a prefix is found (e.g.,
21), then before the call is routed to the corresponding Trunk
Group, the prefix (21) is removed from the original number, and
therefore, only 100 remains.
Notes:
 This parameter is applicable only if number manipulation is
performed after call routing for IP-to-Tel calls (i.e.,
RouteModeIP2Tel parameter is set to 0).
 Similar operation (of removing the prefix) is also achieved by
using the usual number manipulation rules.
[UseReferredByForCallingNumb
er]
Determines whether the device uses the number from the URI
in the SIP Referred-By header as the calling number in the
outgoing Q.931 Setup message, when SIP REFER messages
are received.
 [0] = (Default) No
 [1] = Yes
Notes:
 This parameter is applicable to all ISDN (TBCT, RLT, ECT)
and CAS blind call transfers (except for in-band) and when
the device receives SIP REFER messages with a Referred-
By header.
 This manipulation is done before regular IP-to-Tel source
number manipulation.
