5.8.3 Configuring the 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 IPTel calls
• Destination Phone Number Manipulation Table for TelIP call
• Source Phone Number Manipulation Table for IPTel calls
• Source Phone Number Manipulation Table for TelIP calls
Note: Number manipulation can be performed 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 Table 5-13) and the ‘Tel
to IP Routing Mode’ (described in Table 5-12) parameters.
Possible uses for number manipulation can be as follows:
• To strip/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.
• Assignment of NPI/TON to TelIP calls. The VoIP gateway can use a single global setting
for NPI/TON classification or it can use the setting in this table on a call by call basis. Control
for this is done using “Protocol Management>Protocol Definition>Destination/Source Number
Encoding Type”.
• Allow / disallow Caller ID information to be sent according to destination / source prefixes.
For detailed information on Caller ID refer to Section
5.8.8.3 on page 94.
To configure the Number Manipulation tables, take these 5 steps:
1. Open the Number Manipulation screen you want to configure (Protocol Management menu
> Manipulation Tables submenu); the relevant Manipulation table screen is displayed.
Figure
5-10 shows the ‘Source Phone Number Manipulation Table for TelIP calls’.

2. In the ‘Table Index’ drop-down list, select the range of entries that you want to edit (up to 20
entries can be configured for Source Number Manipulation and 50 entries for Destination
Number Manipulation).
3. Configure the Number Manipulation table according to Table
5-8.
4. Click the Submit button to save your changes.
5. To save the changes so they are available after a power fail refer to Section
5.12 on page
