Table 3: Operational Error Conditions for 1600 Series IP Deskphones (continued)
Condition
The deskphone works properly, except
incoming DTMF tones are not received.
The deskphone works properly, except
sidetone DTMF is not heard.
Hands-Free Answer (HFA) is administered
but the deskphone did not automatically
answer a call.
The HTTP/HTTPS script file and settings file
are ignored (not being used by the
deskphone).
The HTTP/HTTPS
script file is ignored
or not used by the
deskphone,

AND the HTTP/
HTTPS server is a
LINUX or UNIX
system.
AND deskphone
administration
recently changed.
Cause/Resolution
CAUSE: The TN2302AP board does not pass
in-band DTMF tones.
RESOLUTION: None; the board is operating as
designed.
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.
CAUSE: HFA only works if the deskphone 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.
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.
CAUSE: The deskphone 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 <Carriage Return>s from the
file. Doing so causes the entire file to be treated
as a comment, and thus be ignored.
RESOLUTION: Edit the script file with a
®
Windows -based editor, or another editor that
does not strip out the <Carriage Return>.
CAUSE: UNIX and LINUX systems use
case-sensitive addressing and file labels.
RESOLUTION: Verify the file names and path in
the script file are accurately specified.
CAUSE: The 16xxupgrade.txt file was edited
incorrectly, renamed, etc.
RESOLUTION: Download a clean copy of the
16xxupgrade.txt file from the Avaya support
Web site at http://www.avaya.com/support, and
do not edit or rename it. Customize or change
only the 46xxsettings file, as discussed in
Chapter 4: Maintaining 1600 Series IP
Telephones.
