Configuring number manipulation for Source Phone Numbers for
Norstar to IP calls
This number manipulation table is used to manipulate or assign NPI / TON values to the source
number used for the call setup. Generally speaking, this table is not used since the source phone
number is a statically set parameter for the VoIP Gateway.
Source phone numbers are entered into the VoIP Gateway in the Channels – Hunt Group table. In
that table, a phone number can be entered for each port of the VoIP Gateway. This number may be
different from port to port, which is appropriate for a system that uses a key system style of line
appearances, or could be the same, which is appropriate for a system that uses the PBX system of
line pools.
The source number in an H.323 message is used to identify the caller for use in calling line ID
presentation. As such, manipulation of the source digits would normally only need to be done in
order to change the digits so that they will be in a more appropriate form for calling line ID.
For example, the VoIP Gateway may be setup so that it reflects the telephone number used in the
private dialing plan. Source manipulation can then be used to transform that private number into a
public dialing plan number that represents the normal PSTN number that would be used to dial the
location.
The source manipulation table may also be used to assign a specific NPI / TON classification to
the calling number. Setting an NPI / TON can be done globally or values used in this table can be
applied. Control for this is done using “Protocol Management / Protocol Definition / Source
Number Encoding Type”

Note: The Save Configuration option is useful for trying out a new configuration.
Simply make the change and try out the new configuration. If you are happy with the
new configuration, save the changes to non-volatile memory. If you are not happy
with the new configuration, do not save the changes to non-volatile memory and
remove power from the VoIP Gateway. The VoIP Gateway will return to the previous
configuration.
