4600 Series IP Telephone Release 2.1 LAN Administrator's Guide
Cause/Resolution
CAUSE: PBX suppresses sidetone DTMF.
RESOLUTION: On PBX administration, on the
Change-System-Parameters screen, enable On-Hook
Dialing. If the user has Hands-Free Answer (HFA) and
answers the call on the telephone's speakerphone, then
switches to the handset, pressing the 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 telephone is idle. If a
second call comes into the telephone while the first call is
in progress (including ringing before the first call is
answered), the second call is ignored.
RESOLUTION: None.
CAUSE: Non-Avaya shareware or freeware TFTP
applications often cease operating to request registration.
RESOLUTION:
Short-term: Restart the application.
Long-term: Register the product or replace it with an
application that does not behave this way (for example,
Avaya's TFTP application).
CAUSE: The telephone expects lines of the script file to
terminate with a
<Carriage Return> <Line Feed>
Some UNIX applications only terminate lines with
. Editing the script file with a UNIX-based
<Line Feed>
editor can strip
<Carriage Return>
causing 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 46xxupgrade.scr file was mis-edited,
renamed, etc.
RESOLUTION: Download a clean copy of the
46xxupgrade.scr file from the Avaya Support Web site,
and do not edit or rename it. Make any customization
changes only to the 46xxsettings file, as discussed in
Chapter 4, "Server Administration".
CAUSE: The TFTP server hangs if power is interrupted
while a telephone is saving the application file.
RESOLUTION: Restart the TFTP server.
