5.5.3 Configuring the Number Manipulation Tables
The VoIP gateway provides four Number Manipulation tables for incoming and outgoing
calls. These tables are used to modify the destination and source telephone numbers so
that the calls can be routed correctly.
The Manipulation Tables include:
„ Destination Phone Number Manipulation Table for IP-to-Tel calls
„ Destination Phone Number Manipulation Table for Tel-to-IP calls
„ Source Phone Number Manipulation Table for IP-to-Tel calls
„ Source Phone Number Manipulation Table for Tel-to-IP calls
Note:
Number manipulation can occur either before or after a routing decision is
made. For example, you can route a call to a specific hunt (analog module) or
trunk (digital module) group according to its original number, and then you
can remove / add a prefix to that number before it is routed. To control when
number manipulation is done, define the IP to Tel Routing Mode
(RouteModeIP2Tel), described in 'IP to Hunt Group Routing' on page
132 ,
and Tel to IP Routing Mode (RouteModeTel2IP) described in 'Tel to IP
Routing Table' on page
129 .
Possible uses for number manipulation can be as follows:
„ To strip or add dialing plan digits from or to the number. For example, a user could dial
9 in front of each number to indicate an external line. This number (9) can be removed
before the call is setup.
„ Allow or disallow Caller ID information to be sent according to destination or source
prefixes. For detailed information on Caller ID, refer to the
SIP Series Reference
Manual
.
For configuring the Number Manipulation Tables, you can also use the following
ini
file
parameters (refer to 'Number Manipulation and Routing Parameters' on page 304 ):
„ NumberMapTel2IP: configures the Destination Phone Number Manipulation Table for
Tel to IP Calls
