Troubleshooting the 4601 IP Telephone
Issue 6 February 2007 93
Extension
in Use
VISUAL INDICATION: If the extension is currently being used and a first
registration attempt is made, the Message Waiting indicators at the top of
telephone and left middle of the faceplate display a broken flutter
(alternating 50 milliseconds on, 50 milliseconds off for 500 milliseconds
followed by 500 milliseconds off) five times, then flash continuously,
awaiting user entry. Making a second registration attempt using the same
extension causes the Message Waiting indicators to display a continuous
broken flutter, alternating 50 milliseconds on, 50 milliseconds off for 500
milliseconds followed by 500 milliseconds off. In addition, Call Appearance
Line b’s LED flashes continuously until either the “*” or “#” button is
pressed.
CAUSE: The PBX detects an extension conflict with an existing set or
Softphone.
RESOLUTION: You can force the current telephone to register, and
thereby disconnect the other user, by pressing #. The 4600 Series IP
Telephone prompts you again for the extension and password. If you enter
the same extension and password, you must confirm that you want to
unregister the original user. Press # to unregister the original user and
register the current telephone. Then press * to reset the telephone and
enter a different extension and password. If no action is taken within 20
minutes, the telephone attempts re-registration and repeats the process
until you intervene or power is lost.
IP address
in use by
another
VISUAL INDICATION: All LEDs are steadily lit, except Call Appearance
Line a, which is flashing.
CAUSE: The telephone has detected an IP Address conflict.
RESOLUTION: DHCP restart is automatically initiated. No user action
required.
No Ethernet VISUAL INDICATION: No LEDs flash when telephone is plugged in.
CAUSE: Telephone is not receiving power or when first plugged in, the IP
telephone is unable to communicate with the Ethernet.
RESOLUTION: Verify the connection to the Ethernet jack, verify the jack is
Category 5, verify power is applied on the LAN to that jack, etc.
Password
Error
VISUAL INDICATION: Message Waiting indicators at top of telephone
and left middle of faceplate display a broken flutter for a total of 5 cycles
(with one cycle being alternating 50 milliseconds on, 50 milliseconds off for
500 milliseconds followed by 500 milliseconds off), then flash continuously,
awaiting user entry.
CAUSE: The PBX does not recognize the password entered.
RESOLUTION: Confirm the password is correct, then try registration
again, taking particular care to enter the password accurately.
