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.
Note: The parameter is applicable only to digital interfaces.
Add NPI and TON to Called
Number
configure voip > gateway
routing settings > npi-n-ton-
to-cld-nb
[AddNPIandTON2CalledNu
mber]
Determines whether NPI and TON are added to the Called Number for
Tel-to-IP calls.

[0] No = (Default) Do not change the Called Number.

[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.
Note: The parameter is applicable only to digital interfaces.
Add NPI and TON to
Redirect Number
np-n-ton-2-redirnb
[AddNPIandTON2RedirectN
umber]
Determines whether the NPI and TON values are added as the prefix to
the Redirect number in INVITE messages' Diversion or History-Info
headers, for ISDN Tel-to-IP calls.

[0] Yes (Default)

[1] No
Note: The parameter is applicable only to digital interfaces.
IP to Tel Remove Routing
Table Prefix
configure voip > gateway
routing settings > ip2tel-
rmv-rte-tbl
[RemovePrefix]
Determines whether or not the device removes the prefix, as configured
in the IP-to-Tel Routing table (see Configuring IP-to-Tel Routing Rules
on page 504) from the destination number for IP-to-Tel calls, before
sending it to the Tel.

[0] No (default)

[1] Yes
For example: To route an incoming IP-to-Tel call with destination
number "21100", the IP-to-Tel 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.
Note:

The 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.
Swap Redirect and Called
Numbers
swap-rdr-n-called-nb
[SwapRedirectNumber]

[0] No = (Default) Don't change numbers.

[1] Yes = Incoming ISDN call that includes a redirect number
(sometimes referred to as 'original called number') uses the redirect
number instead of the called number.
Note: The parameter is applicable only to digital interfaces.
configure voip > gateway
manipulation settings > use-
refer-by-for-calling-num
[UseReferredByForCallingN
umber]
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
Note:

The parameter is applicable to all ISDN (TBCT, RLT, ECT) and CAS
blind call transfers (except for in-band) and when the device receives
