SIP Registration
The SIP Registration page is used to configure the SIP registrar and proxy settings and
the SIP account and user settings for the phone. The minimum number of information
required to register your phone is the Registrar, the Username and Password. If ID and
Display Name are not set, FLX will use the user name for both of these parameters.
Some IP PBXs an ID different from the user name to be set. You must register
successfully to the SIP registrar before you can make calls with your FLX.
The figure below shows the SIP Registration page. After changing any settings, the
changes must be saved and the phone must be restarted for the changes to take effect.
The table below describes the SIP Registration settings. Different IP PBX providers
might use different names in their setup. The descriptions below will help you in
mapping the FLX fields to your IP PBX fields.
