7.5 User Information File
The User Information file is a text file that maps PBX extensions connected to the device to
global IP numbers. In this context, a global IP phone number (alphanumerical) serves as a
routing identifier for calls in the 'IP world'. The PBX extension uses this mapping to emulate
the behavior of an IP phone.
Note: By default, the mapping mechanism is disabled and must be activated using
the parameter EnableUserInfoUsage.
The maximum size of the file is 10,800 bytes (for analog modules) and108,000 bytes for
digital modules. Each line in the file represents a mapping rule of a single PBX extension.
Up to 1,000 rules can be configured. Each line includes five items separated with commas.
The items are described in the table below:
Table 7-1: User Information Items
Item Description Maximum Size
(Characters)
PBX extension #
The relevant PBX extension number. 10
Global phone #
The relevant global phone number. 20
Display name
A string that represents the PBX extensions for the
Caller ID.
30
Username
A string that represents the user name for SIP
registration.
40

20
Note: For FXS ports, when the device is required to send a new request with the
‘Authorization’ header (for example, after receiving a SIP 401 reply), it uses
the user name and password from the Authentication table. To use the
username and password from the User Info file, change the parameter
‘Password’ from its default value.
An example of a User Information file is shown in the figure below:
