WLAN IP Telephony Handset Users Guide
Overview
The
WLAN IP Telephony Handsets use VoIP technology on IEEE 802.11-
compliant Wireless LAN. Access Points (APs) use radio frequencies to
transmit signals to and from the WLAN handsets.
The WLAN IP Telephony handsets can be used to make and receive calls as
the user moves throughout the building. The WLAN handsets are used only
on the premises; they are not cellular phones. Just like wired telephones, the
WLAN handsets receive calls directly, receive transferred calls, transfer calls
to other extensions, and make outside and long-distance calls. The DN of the
WLAN handset is obtained directly from the BCM system. Therefore IP
Terminal Clients keycodes are required and IP Terminal Registration must be
enabled on the BCM before the WLAN handset can be registered.
Language
The menus and screens of the WLAN IP Telephony Handsets display in
English only. International characters are supported for BCM prompts,
depending on the market profile. BCM-based prompts display in English,
French, and Spanish.
Wired Equivalent Privacy
The WLAN IP Telephony Handsets support Wired Equivalent Privacy (WEP)
as defined by the 802.11b specification. WEP increases the security of the
wireless LAN to a level similar to a wired Ethernet LAN. WEP is turned on and
off using the APs.
Loss of signal
If a wireless handset is out of range of all APs, it waits 20 seconds for a signal
to be re-established. If a signal is not obtained within 20 seconds, the wireless
handset loses connection to the BCM and any calls are dropped. When the
wireless handset comes back into range of an Access Point, it re-establishes
a connection to the BCM and goes through the system registration process.
IP Phone i2004 mapping
The WLAN IP Telephony Handsets emulate the IP Phone 2004. All IP Phone
2004 functions and messaging features are supported, where possible. The
speakerphone function and functions that require use of the volume keys are
not supported.
