3.4.5.9.1 Configuring the Number Manipulation Tables
The device provides four number manipulation tables for incoming (IP-to-Tel) and outgoing
(Tel-to-IP) calls. These tables are used to modify the destination and source telephone
numbers so that the calls can be routed correctly. For example, telephone number
manipulation can be implemented for the following:
îš„ 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.
îš„ Allowing or blocking Caller ID information to be sent according to destination or source
prefixes. For detailed information on Caller ID, refer to Configuring Caller Display
Information on page 214.
The num
ber manipulation is configured in the following tables:
îš„ For Tel-to-IP calls:
• Destination Phone Number Manipulation Table for Tel-to-IP Calls
(NumberMapTel2IP ini file parameter) - up to 100 entries
• Source Phone Number Manipulation Table for Tel-to-IP Calls
(SourceNumberMapTel2IP ini file parameter) - up to entries
îš„ For IP-to-Tel calls:
• Destination Phone Number Manipulation Table for IP-to-Tel Calls
(NumberMapIP2Tel ini file parameter) - up to 100 entries
• Source Phone Number Manipulation Table for IP-to-Tel Calls
(SourceNumberMapIP2Tel ini file parameter) - up to 20 entries
The device matches manipulation rules starting at the top of the table. In other words, a rule
at the top of the table takes precedence over a rule defined lower down in the table.
Therefore, define more specific rules above more generic rules. For example, if you enter
551 in Index 1 and 55 in Index 2, the device applies rule 1 to numbers that start with 551
and applies rule 2 to numbers that start with 550, 552, 553, and so on untill 559. However,
if you enter 55 in Index 1 and 551 in Index 2, the device applies rule 1 to all numbers that
start with 55, including numbers that start with 551.
