Configuring The Number Manipulation Tables - 3Com VCX v7111 User Manual

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 are:
Destination Phone Number Manipulation Table for IP Tel calls
Destination Phone Number Manipulation Table for Tel IP call
Source Phone Number Manipulation Table for IP Tel calls
Source Phone Number Manipulation Table for Tel IP calls
Number manipulation can occur either 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 / add a prefix to that number before it is routed.
To control when number manipulation is done, set the IP to Tel Routing Mode
(described in
parameters.
Possible uses for number manipulation can be as follows:
To strip or add dialing plan digits from/to the number. For example, a user could dial 9 in
front of each number in order to indicate an external line. This number (9) can be
removed here before the call is setup.
Allow or disallow Caller ID information to be sent according to destination / source
prefixes. For detailed information on Caller ID, see
