Troubleshooting
For corded telephone
Question Suggestions
1. The telephone does not work at all.
• Make sure a Cat-5 network cable is
plugged into the LAN port of the telephone
base and the network wall jack with Power
over Ethernet (PoE).
• Unplug the Cat-5 network cable from the
network wall jack. Wait for approximately
15 seconds, then plug it back in.
• Disconnect the telephone base from the
network wall jack and connect a different
working telephone. If the other telephone
does not work, the problem is probably in
the wiring or network server.
2. There is no dial tone.
• Try all the above suggestions.
• The Cat-5 network cable may be defective.
Install a new Cat-5 network cable.
• Make sure your network is providing Power
over Ethernet (PoE).
• Disconnect the telephone base from the
network wall jack and connect a different
working telephone. If there is no dial tone
on this telephone either, the problem is in
your wiring or network server.
• Make sure the initialization and system
registration process completes. The
speakerphone key blinks twice every second
if there are errors with the initialization and
system registration process.
3. I hear other calls when using the telephone.
• Disconnect the telephone base from
the network wall jack and connect a
different working telephone. Check your
server settings. If calls are still not clear,
the problem is probably in the wiring or
network server. Contact your telephone
service provider (charges may apply).
4. The Speed Dial key does not work at all.
• The Speed Dial key may not be properly
programmed.
