V6100 and V7122 User Guide 381User Information FileThe User Information file maps PBX extensions to global IP numbers. In this context, aglobal IP number serves as a routing identifier for calls in the ‘IP World’. The PBX extensionuses this mapping to emulate the behavior of an IP phone. Note that the mappingmechanism is disabled by default and must be activated using the parameter‘EnableUserInfoUsage’ (described in SIP Configuration Parameters).Each line in the file represents a mapping rule of a single PBX extension (up to 1000 rulescan be configured). Each line includes five items separated with commas. The items aredescribed in Table 79. An example of a User Information file is shown in Figure 130.Each PBX extension registers (and authenticated) separately (a REGISTER message is sentfor each entry, only if AuthenticationMode is set to ‘Per Endpoint’) using the IP number in theFrom / To headers. The REGISTER messages are sent gradually (i.e., initially, the gatewaysends requests according to the maximum number of allowed SIP dialogs (configured by theparameter NumberOfActiveDialogs), after each received response, the subsequent requestis sent). Therefore, no more than ‘NumberOfActiveDialogs’ dialogs are activesimultaneously. 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 (ifdefined) the manipulation rules are performed. The Display Name is used in the Fromheader in addition to the IP number.The called number of incoming IP to Tel calls is translated to a PBX extension only aftermanipulation rules (if defined) are performed.The User Information file is a text file (the file size mustn’t exceed 106,000 bytes) that can beloaded via the ini file (UserInfoFileName, described in Configuration Files Parameters), theEmbedded Web Server (see Auxiliary Files) or by using the automatic update mechanism(UserInfoFileURL, see Automatic Update Mechanism).Table 79 User Information ItemsItem Description Maximum SizePBX extension # The relevant PBX extension number 10Global IP # The relevant IP number 20Display name A string that represents the PBX extensionsfor the Caller ID. 30Username A string that represents the username forSIP registration. 20Password A string that represents the password for SIPregistration. 20
