and so on until 559. However, if you enter 55 in Index 1 and 551 in Index 2, the device
applies rule 1 to all numbers that start with 55, including numbers that start with 551.
You can perform a second "round" (additional) of destination (NumberMapIP2Tel
parameter) and source (SourceNumberMapIP2Tel parameter) number manipulations for
IP-to-Tel calls on an already manipulated number. The initial and additional number
manipulation rules are both configured in these tables. The additional manipulation is
performed on the initially manipulated number. Therefore, for complex number
manipulation schemes, you only need to configure relatively few manipulation rules in
these tables (that would otherwise require many rules). This feature is enabled using the
following parameters:

PerformAdditionalIP2TELSourceManipulation for source number manipulation

PerformAdditionalIP2TELDestinationManipulation for destination number manipulation
Telephone number manipulation can be useful, for example, for the following:

Stripping or adding dialing plan digits from or to the number, respectively. For
example, a user may need to first dial 9 before dialing the phone number to indicate
an external line. This number 9 can then be removed by number manipulation before
the call is setup.

Allowing or blocking Caller ID information according to destination or source prefixes.
For more information on Caller ID, see Configuring Caller Display Information on page
404.

For digital modules only: Assigning Numbering Plan Indicator (NPI) and Type of
Numbering (TON) to IP-to-Tel calls. The device can use a single global setting for
NPI/TON classification or it can use the setting in the manipulation tables on a call-by-
call basis.
Notes:
• Number manipulation can occur before or after a routing decision is
made. For example, you can route a call to a specific Trunk Group
according to its original number, and then you can remove or add a prefix
to that number before it is routed. To determine when number
manipulation is performed, configure the 'IP to Tel Routing Mode'
parameter (RouteModeIP2Tel) described in 'Configuring Inbound IP
Routing Table' on page 336, and 'Tel to IP Routing Mode' parameter
(RouteModeTel2IP) described in 'Configuring Outbound IP Routing
Table' on page 327.
• The device manipulates the number in the following order: 1) strips digits
from the left of the number, 2) strips digits from the right of the number,
3) retains the defined number of digits, 4) adds the defined prefix, and
then 5) adds the defined suffix.
• The source/destination number manipulation tables can also be
configured using the ini file and CLI:
1) Destination Phone Number Manipulation Table for IP > Tel Calls
table: NumberMapIP2Tel (ini); configure voip/gw manipulations dst-
number-map-ip2tel (CLI)
2) Destination Phone Number Manipulation Table for Tel > IP Calls
table: NumberMapTel2IP (ini); configure voip/gw manipulations dst-
number-map-tel2ip (CLI)
3) Source Phone Number Manipulation Table for IP > Tel Calls table:
SourceNumberMapIP2Tel (ini); configure voip/gw manipulations src-
number-map-ip2tel (CLI)
4) Source Phone Number Manipulation Table for Tel > IP Calls table:
SourceNumberMapTel2IP (ini); configure voip/gw manipulations src-
number-map-tel2ip (CLI)
