Notes:
1. The "xsi allow sip authentication" parameter is disabled by default.
2. As detailed in the examples above, the user name portion of the "sip xsi user name"
and "sip lineN xsi user name" parameters corresponds to the same value as the
"sip auth name" and "sip lineN auth name".
3. If using a per-line XSI SIP authentication configuration, depending on which line is
in focus on the phone, the Xsi features will reflect the account that has been
configured for that line. For example, with Xsi Basic Calls Logs enabled, pressing
the Callers List key on the phone when Line 3 is in focus on the phone will display
the call logs for the account configured for Line 3.
