Issue 2.2 April 2005 103
The telephone works properly except for the
Speaker.
CAUSE: The Speaker was turned off on the
PBX.
RESOLUTION: Administer the PBX to allow
that station’s Speaker to operate. If that does
not work, do a Self-test on the telephone.
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: 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), 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 TFTP application terminates and asks for
registration.
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.
The TFTP or HTTP 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.
