SpectraLink Wireless Telephone Overview

During the last three steps of this process, the handset contacts the SIP
TFTP server and downloads general information about the proxy
server(s), downloads specific information pertaining to the handset,
registers with the proxy server(s), and verifies handset credentials.
Once this process is complete, the handset is ready to use.
If the username and password have not been defined in the Admin
menu, you will be prompted to enter both of these items before the
extension number can display. The user name must correspond to the
configuration file that contains user-specific information. If the file is
not found, an error message will appear and the handset will restart.
See Chapter 5 Programming the SIP Handset Features, section SIP TFTP
Server Configuration Files.
Handset Modes
Standby mode (on-hook)
In standby mode, the handset is waiting for an incoming call or for
the user to place an outgoing call. The extension number is shown on
the display and there is no dial tone. In this mode, the handset is
conserving battery power and wireless LAN bandwidth.
When an incoming call arrives, the handset rings; the handset enters
the active mode and remains so until the call is ended. The call is
answered by pressing the
START key or the Answ softkey. The handset
will ring according to user preference as specified in the standby
menus. The ringing can be silenced by pressing the
END key. If you do
not wish to accept the call, press the
Rej softkey. The SIP server (if
present) will redirect the call as configured by the system
administrator, often to voicemail. (Treated like the handset is busy.)
Active mode (off-hook)
The handset is in the active mode when an incoming call is answered
or when it is in communication with the SIP server without being in
an active call.
When an incoming call occurs during an active call, the handset will
play the second call ringing sound until the call is answered, the caller
hangs up, or the call transfers to voicemail. If the
END key is pressed,
the first call is terminated and the handset reverts to a full ring.
