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.
Telephone number manipulation can be implemented for the following usage examples:
Strip or add dialing plan digits from or to the number. 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 the Manipulation table) before the call is setup.
Allow or disallow Caller ID information to be sent according to destination or source
prefixes. For detailed information on Caller ID, refer to Caller Display Information on
page 174.
The number manipulation is performed in the following tables:
Destination Phone Number Manipulation Table for IP-to-Tel Calls (NumberMapIP2Tel
ini file parameter)
Destination Phone Number Manipulation Table for Tel-to-IP Calls (NumberMapTel2IP
ini file parameter)
Source Phone Number Manipulation Table for IP-to-Tel Calls
(SourceNumberMapIP2Tel ini file parameter)
Source Phone Number Manipulation Table for Tel-to-IP Calls
(SourceNumberMapTel2IP ini file parameter)
Notes:
To configure the Number Manipulation tables, take these 5 steps:
1. Open the required 'Number Manipulation' page (Configuration tab > Protocol
Configuration menu > Manipulation Tables submenu > Dest Number IP->Tel,
Dest Number Tel->IP, Source Number IP->Tel, or Source Number Tel->IP page
item); the relevant Manipulation table page is displayed (e.g., 'Source Phone Number
Manipulation Table for Tel IP Calls' page).
SIP User's Manual
•
Number manipulation can occur 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 or add a prefix
to that number before it is routed. To determine when number
manipulation is performed, configure the 'IP to Tel Routing Mode'
parameter (RouteModeIP2Tel) described in ''IP to Hunt Group Routing''
on page 159, and 'Tel to IP Routing Mode' parameter (RouteModeTel2IP)
described in ''Tel to IP Routing Table'' on page 156.
•
For configuring number manipulation using ini file table parameters
NumberMapIP2Tel, NumberMapTel2IP, SourceNumberMapIP2Tel, and
SourceNumberMapTel2IP, refer to ''Number Manipulation and Routing
Parameters'' on page 286.
