Table 14: Some Error Conditions in Operation of 4600 Series IP Telephones (continued)
Condition
The telephone works properly except for the
Speaker.
The telephone works properly, except
incoming DTMF tones are not received.
The telephone works properly, except
sidetone DTMF is not heard.
Hands-Free Answer (HFA) is administered
but the telephone did not automatically
answer a call.
The TFTP application terminates and asks for
registration.
The TFTP or HTTP script file and settings file
are ignored (not being used by the
telephone).
Cause/Resolution
CAUSE: The Speaker was turned off on the
PBX (H.323 telephones) or the 46xxsettings
file's SPEAKERSTAT parameter is set to "0"
(SIP telephones).
RESOLUTION: Administer the PBX to allow
that station's Speaker to operate (H.323
telephones) or change the SPEAKERSTAT
parameter value (SIP telephones). If that does
not work, do a Self-test on the telephone, as
explained in the 4600 Series IP Telephone
Installation Guide.
CAUSE: The TN2302AP circuit pack does not
pass in-band DTMF tones.
RESOLUTION: None; the board is operating
as designed.
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.
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.
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 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.
