SIP User's Manual 3. Web-Based Management
Parameter Description
[AddNPIandTON2CallingNumber]
for Tel-to-IP calls.
ƒ
[0]
No = Do not change the Calling Number (default).
ƒ
[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.
Add NPI and TON to Called Number
[AddNPIandTON2CalledNumber]
Determines whether NPI and TON are added to the Called
Number for Tel-to-IP calls.
ƒ
[0]
No = Do not change the Called Number (default).
ƒ
[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.
IP to Tel Remove Routing Table Prefix
[RemovePrefix]
Determines whether the device removes the prefix from the
destination number for IP-to-Tel calls.
ƒ
[0]
No = Don't remove prefix (default)
ƒ
[1]
Yes = Remove the prefix (defined in the 'IP to Trunk
Group Routing' table - refer to ''IP to Trunk Group
Routing'' on page
181 ) 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 'IP to Trunk Group 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:
ƒ
Applicable only if number manipulation is performed after
call routing for IP-to-Tel calls (i.e., RouteModeIP2Tel
parameter is set to 0).
ƒ
Similar operation (of removing the prefix) is also
achieved by using the usual number manipulation rules.
Source IP Address Input
[SourceIPAddressInput]
Determines the IP address that the device uses to
determine the source of incoming INVITE messages for IP-
to-Tel routing.
ƒ
[-1]
= Not configured (default).
ƒ
[0]
SIP Contact Header = Use the IP address received in
the Contact header of the incoming INVITE message.
ƒ
[1]
Layer 3 Source IP = Use the actual IP address (Layer
3) from which the SIP packet was received.
Note:
If the IP-to-IP feature is enabled (i.e., supported by
the Feature Key and EnableSBC is set to 1 - refer to “SBC
Configuration” on page
163 ), this parameter is automatically
set to 1. If the IP-to-IP feature is disabled, this parameter is
automatically set to 0.
