Cisco VoIP - Basic Troubleshooting for Desk Phones
Basic troubleshooting steps for issues with a Cisco VoIP desk phone. Should be used for issues like being unable to place calls, screen is not functioning, phone is frozen, etc.
1.
Unplug the phone from
power, wait 5 seconds and plug it back in.
2.
Check the power source.
1.
Is the power cable
plugged into the wall?
2.
Check the connection
between the power cable and the power cube, this can become loose. (Note, this
is located between the phone and the wall)
3.
Is the power cable plug
securely into the back of the phone?
3.
Check the Ethernet
connection. Cable configuration should be data jack to phone to computer.
1.
Is the cable plugged
securely into the wall jack?
2.
Is the cable plugged
securely into the network port (3 box symbol) on the phone?
The cable should lead from the wall port directly to the phone.
3.
Is the cable plugged
securely into the computer? The cable should lead from the PC port (1
box symbol) on the phone directly to the computer.
4.
Are any of the cable
connections loose or poorly fitted? The cable should not be jammed into a jack
but it also should not be wiggly. Old cables are a common issue. If you can
hold the cable a “certain way” in the jack and the Ethernet reconnects this is
an indicator of a bad cable. If this is a problem, please replace the cable.
4.
Check handset cord.
1.
Is the handset cord securely
plugged in to the handset and back of the phone?
2.
Is the handset cord
plugged in to the handset port?
5.
If none of these fix
your problems, please contact the DoIT Help Desk. Please be ready with the
following information:
1.
The MAC address of the
phone 86228
2.
The model of the phone.
3.
The room and building
where it is located.
4.
The jack number where it
is plugged in.
