SIP User's Manual 332 Document #: LTRT-65408
15.4 User Information File
The User Information file maps PBX extensions (connected to the MediaPack gateway) to
global IP phone numbers (alphanumerical). In this context, a global IP number 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 that the mapping mechanism is disabled by
default and must be activated using the parameter ‘EnableUserInfoUsage’ (described in
Section 5.5.2.1).
Each line in the file represents a mapping rule of a single PBX extension (up to 100 rules
can be configured). Each line includes five items separated with commas. The items are
described in Table 15-1 below. An example of a User Information file is shown in Figure
15-5 below.
Each PBX extension registers separately (a REGISTER message is sent for each entry,
only if AuthenticationMode is set to ‘Per Endpoint’) using the IP number in the From / To
headers. The REGISTER messages are sent gradually (i.e., initially, the gateway sends
requests according to the maximum number of allowed SIP dialogs (configured by the
parameter NumberOfActiveDialogs), after each received response, the subsequent request
is sent). Therefore, no more than ‘NumberOfActiveDialogs’ dialogs are active
simultaneously. The username and password are used for SIP Authentication when
required.
The calling number of outgoing Tel to IP calls is first translated to an IP number and then (if
defined) the manipulation rules are performed. The Display Name is used in the From
header in addition to the IP number.
The called number of incoming IP to Tel calls is translated to a PBX extension only after
manipulation rules (if defined) are performed.
The User Information file is a text file (the file size mustn’t exceed 10,800 bytes) that can
be loaded via the ini file (UserInfoFileName, described in Table 5-64), the Embedded Web
Server (refer to Section 5.9.2 on page 202) or by using the automatic update mechanism
(UserInfoFileURL, refer to Section 10.3 on page 263).
