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:
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
268.
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 230, and 'Tel to IP Routing Mode'
parameter (RouteModeTel2IP) described in 'Configuring Tel to IP
Routing' on page 223.
• 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)
