3.3.2.8.2.2 Configuring Number Manipulation Tables
The device provides number manipulation tables for incoming (IP-to-Tel) and outgoing
(Tel-to-IP) calls. These tables are used to modify the destination and/or source telephone
numbers so that the calls can be routed correctly. For example, telephone number
manipulation can be implemented by 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 according to destination or source prefixes.
For detailed information on Caller ID, see Configuring Caller Display Information on
page 155.
Numb
er manipulation is configured in the following tables:
îš„ Tel-to-IP calls:
• Destination Phone Number Manipulation Table for Tel-to-IP Calls
(NumberMapTel2IP ini file parameter) - up to 120 entries
• Source Phone Number Manipulation Table for Tel-to-IP Calls
(SourceNumberMapTel2IP ini file parameter) - up to 20 entries
