Condition Cause/Resolution
volume level which
are worse when the
Speaker is on, or at
the beginning of a
call, or when a call
goes from no one
talking abruptly to a
loud voice.
acoustics are not consistent with the current
audio settings.
RESOLUTION: Try different on/off settings for
the AGCHAND, AGCHEAD, and AGCSPKR
parameters.
The telephone works properly except for
the Speaker.
CAUSE: The Speaker was turned off at the call
server.
RESOLUTION: Administer the call server to
allow that station’s Speaker to operate. If that
does not work, do a self-test on the telephone,
as explained in the
Performing a self-test on
page 58.
The telephone works properly, except
incoming DTMF tones are not received.
CAUSE: The TN2302AP board does not pass
in-band DTMF tones.
RESOLUTION: None; the board is operating
as designed.
The telephone works properly, except
sidetone DTMF is not heard.
CAUSE: Call server suppresses sidetone
DTMF.
RESOLUTION: On call server administration,
on the Change-System-Parameters screen,
enable On-Hook Dialing. If the user has
Hands-Free Answer (HFA), answers a call
using the Speaker and switches to the
handset, pressing dialpad buttons does not
send DTMF tones. This is a known bug, and
the only current resolution is to disable HFA.
Hands-Free Answer (HFA) is administered
but the telephone did not automatically
answer a call.
CAUSE: HFA only works if the telephone is
idle. A second call is ignored if it comes in while
a call is in progress, including ringing before
the first call is answered.
RESOLUTION: None.
The HTTP/HTTPS script file and settings
file are ignored (not being used by the
telephone).
CAUSE: The system value AUTH is set to 1
(HTTPS required) but no valid address is
specified in TLSSRVR.
RESOLUTION: Change AUTH to 0 (zero), or
enter a valid address for TLSSRVR.
The HTTP/HTTPS
script file is
ignored or not
used by the
telephone,
AND the HTTP/
HTTPS server is a
LINUX or UNIX
system.
CAUSE: The telephone expects lines of the
script file to terminate with a <Carriage
Return> <Line Feed>. Some UNIX
applications only terminate lines with <Line
Feed>. Editing the script file with a UNIX-
based editor can strip a<Carriage
