Linksys SPA9x2 Phone Administration Guide Cisco Confidential--First Draft5
Additional Phone Features
Introducing Linksys SPA9x2 Phones
– Switching of lower microphone gain to reduce saturation.
– Noise floor estimation using voice activity detection (VAD).
• Phone LCD features:
– The screen can display the header of the 18X call progress message instead of
displaying “Called Party Ringing.”
– A screen saver can appear when the phone is in an idle state for a period of time.
– A customized service provider logo can be downloaded to display during boot-up.
– A customized background picture can be downloaded to display on SPA942 and
SPA962 phones.
– The SPA962 can display photos in a “photo album effect” using the HTTP REFRESH
feature.
• Emergency Numbers
– An administrator can enter a list of emergency numbers in the Emergency Number
parameter. When one of these numbers is dialed on an IP phone, the unit disables
processing of “CONF”, “HOLD”, and other similar softkeys or buttons to avoid
accidentally putting the current call on hold. In addition, only the far end can
terminate an emergency call. See ”Dial Plan Parameters” section on page 105.
• GUI Localization: SPA9x2 phone menus can display in languages other than English.
– Additional Character Sets Supported on Phones include Latin2 (Czech, Hungarian,
Polish, Romanian, Croatian, Slovak, Slovenian, Sorbian), Cyrillic (Russian, Bulgarian,
Ukrainian and others), and Latin5 (Turkish). The phones officially support the ISO-
8859-1 to 8859-16 character sets, which encompass all Eastern and Western
European languages.
• CALEA Compliance : To ensure compliance with the Communications Assistance for Law
Enforcement Act (CALEA) in the United States, privacy setting parameters have been
modified for the SPA9x2. If a user’s privacy settings are activated, the “From” value is not
changed to Anonymous. Instead, the switch equipment masks the caller ID, and the
calls can be tracked as required by US government regulations.
