You can perform a second "round" (additional) of source and destination number
manipulations for IP-to-Tel calls, on an already manipulated number. The initial and
additional number manipulation rules are both configured in the number manipulation
tables for Ip-to-Tel calls. The additional manipulation is performed on the initially
manipulated number. Thus, for complex number manipulation schemes, you only need to
configure relatively few manipulation rules in these tables (that would otherwise require
many rules). To enable this additional manipulation, use the following parameters:

Source number manipulation - PerformAdditionalIP2TELSourceManipulation

Destination number manipulation - PerformAdditionalIP2TELDestinationManipulation
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
463.

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.
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, use the 'IP to Tel Routing Mode' parameter
(RouteModeIP2Tel) described in ''Configuring Inbound IP Routing Table'' on page 392, and
'Tel to IP Routing Mode' parameter (RouteModeTel2IP) described in ''Configuring
Outbound IP Routing Table'' on page 383.
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 following procedure describes how to configure number manipulation rules in the Web
interface. You can also configure this using the following management tools:

Destination Phone Number Manipulation Table for IP > Tel Calls table: ini file
table parameter, NumberMapIP2Tel or CLI command, configure voip/gw
manipulations dst-number-map-ip2tel

Destination Phone Number Manipulation Table for Tel > IP Calls table: ini file
table parameter, NumberMapTel2IP or CLI command, configure voip/gw
manipulations dst-number-map-tel2ip

Source Phone Number Manipulation Table for IP > Tel Calls table: ini file table
parameter, SourceNumberMapIP2Tel or CLI command, configure voip/gw
manipulations src-number-map-ip2tel

Source Phone Number Manipulation Table for Tel > IP Calls table: ini file table
parameter, SourceNumberMapTel2IP or CLI command, configure voip/gw
manipulations src-number-map-tel2ip
