Condition
Cause/Resolution
from no one talking
abruptly to a loud voice.
The phone 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 phone.
The phone works properly, but you cannot hear
incoming DTMF tones.
CAUSE: The TN2302AP board does not pass in-band
DTMF tones.
RESOLUTION: None; the board is operating as
designed.
The phone works properly, but you cannot hear
incoming DTMF tones.
CAUSE: Call server suppresses sidetone DTMF.
RESOLUTION: After completing call server
administration, enable On-Hook Dialing on the
Change-System-Parameters screen. If the user has
enabled Hands-Free Answer (HFA), answers a call
using the Speaker, switches to the handset, and
presses dialpad buttons, the phone does not transmit
DTMF tones. Disable HFA to hear DTMF tones.
Hands-Free Answer (HFA) is administered but
the phone did not automatically answer a call.
CAUSE: HFA only works if the phone is idle. The
phone ignores a second call if a call, including the
ringing tone is in progress.
RESOLUTION: None.
The phone does not use and ignores the HTTP or
HTTPS script file and settings file.
CAUSE: The system value AUTH is set to 1 which
indicates that HTTPS is required but no valid address
is specified in TLSSRVR.
RESOLUTION: Change AUTH to 0 (zero), or enter a
valid address for TLSSRVR.
The HTTP or HTTPS
script file is ignored or
not used by the
phone,
AND the HTTP or
HTTPS server is a
LINUX or UNIX system.
CAUSE: The phone 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 Return>
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.
