Notes:
• Tel-to-IP routing is performed on the original source number if the parameter 'Tel
to IP Routing Mode' is set to 'Route calls before manipulation'.
• Tel-to-IP routing is performed on the modified source number as defined in the
Dial Plan file, if the parameter 'Tel To IP Routing Mode' is set to 'Route calls after

44.1.7 User Information File
This section describes the User Info table and how to configure the table.
44.1.7.1 Enabling the User Info Table
Before you can use the User Info table, you need to enable the User Info functionality as
described in the following procedure.
To enable the User Info table:
1. Open the Advanced Parameters page (Configuration tab > VoIP menu > SIP
Definitions > Advanced Parameters).
2. Set the 'Enable User-Information Usage' parameter (EnableUserInfoUsage) to
Enable.
3. Save this setting to the device with a reset for the setting to take effect.
44.1.7.2 Gateway User Information for PBX Extensions and "Global" Numbers
The GW User Info table contains user information that can be used for the following
Gateway-related features:
Mapping (Manipulating) PBX Extension Numbers with Global Phone Numbers:
maps PBX extension number, connected to the device, with any "global" phone
number (alphanumerical) for the IP side. In this context, the "global" phone number
serves as a routing identifier for calls in the "IP world" and the PBX extension uses this
mapping to emulate the behavior of an IP phone. This feature is especially useful in
scenarios where unique or non-consecutive number translation per PBX is needed.
This number manipulation feature supports the following call directions:
• IP-to-Tel Calls: Maps the called "global" number (in the Request-URI user part) to
the PBX extension number. For example, if the device receives an IP call
destined for "global" number 638002, it changes this called number to the PBX
extension number 402, and then sends the call to the PBX extension on the Tel
side.
Note: If you have configured regular IP-to-Tel manipulation rules (see ''Configuring
Source/Destination Number Manipulation'' on page 469), the device applies these
rules before applying the mapping rules of the User Info table.
