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
307 .
Notes:
•
Number manipulation can occur before or after a routing decision is made. For
example, you can route a call to a specific Hunt 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 IP to
Hunt Group Routing Table' on page
263 , and 'Tel to IP Routing Mode' parameter
(RouteModeTel2IP) described in 'Configuring Tel to IP Routing' on page 256 .
•
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:
1)
Destination Phone Number Manipulation Table for IP > Tel Calls table:
NumberMapIP2Tel (ini)
2)
Destination Phone Number Manipulation Table for Tel > IP Calls table:
NumberMapTel2IP (ini)
3)
Source Phone Number Manipulation Table for IP > Tel Calls table:
SourceNumberMapIP2Tel (ini)
4)
Source Phone Number Manipulation Table for Tel > IP Calls table:
SourceNumberMapTel2IP (ini)
