Troubleshooting LifeSize Phone
The following sections describe symptoms, possible causes, and potential solutions for common
problems you may encounter with your LifeSize Phone.
When experiencing a problem, visually inspect the unit. Ensure the system has not been exposed
to water or heat sources.
For best performance, follow these guidelines:
Position the LifeSize Phone in the center of the room.
Avoid moving the LifeSize Phone during a call.
Speak at normal conversation levels and direct your voice toward the phone.
Port Accessibility
The LifeSize Phone utilizes a port range of 1024 and above. LifeSize Phone utilizes multiple ports
within this range to initiate calls with the far end devices you wish to call.
Incorrect Cabling
Improperly connected or loose cables are common causes of problems with hardware units.
When investigating a system problem, first check all the external controls and cable connections.
Check that connections are correct and secure, and that nothing is obstructing the cables.
Verify that power is supplied correctly to the unit via PoE. If your network connection does not
have PoE you must use a PoE adaptor between the network connection and the phone to supply
power. Inspect connections to any system cables and ensure there are no obstructions or loose
cables at either end.
Ensure you have plugged in the network cable correctly to the PoE adapter or port. Although it is
possible to plug in the LAN end to the phone, the phone will not work. Correct the connection by
reversing the cable to obtain connectivity to your LifeSize Phone.
IP Address Displays Invalid Value
If the IP address displays as, one of the following conditions may be occurring:
The unit is configured to obtain an address using DHCP
and no DHCP server is available.
Verify that the unit is plugged into a network that has a
DHCP server present.
Faulty Ethernet cable connection.
Replace the Ethernet cable with a high-quality cable.
The unit is configured to use a static IP address, but no IP
address has been entered in the address field.
Identify and enter the necessary IP information if you
disable DHCP.
Poor Quality Display
If you have poor quality or unreadable data on the display, adjust the LCD Contrast setting. You
can access User Preferences from the Admin Main Menu on the phone or use the administrator
configuration from a web browser to change this setting. The default setting (20) is
Display Failures
If data does not appear on the phone display, ensure the unit is properly plugged into a PoE
connection. Ensure that the Ethernet connector is fully engaged into the RJ-45 jack on the
underside of the phone. Also ensure that your Ethernet wall jack connection is PoE (standard
Ethernet has no power). A bad Ethernet cable connection may also result in display failures;
replace it with a high-quality Ethernet cable.

volume is adjusted appropriately.
key to initiate a call, ensure the speaker
Problematic Sound Quality
If you are unable to hear the phone ring when an incoming call arrives, the speaker volume may
be set too low. (The LEDs flash blue to indicate an incoming call.) Adjust the volume using the up
and down volume key. If you still experience audio problems, adjust the Ring Tone Volume
preference (on the Audio submenu of the Preferences menu) in the administrator configuration
from the phone or web browser.
Muffled reception may be caused by highly reverberant rooms. If you are experiencing poor
reception, add more sound absorbency to the room and speak closer to the unit.
Adjust the priority order for your audio codec if you have chosen a low-bandwidth audio codec to
be first. Ensure that the far end caller has configured the phone correctly and is in an acoustically
benign environment. For best results, ensure the far end caller is using a LifeSize Phone.
Distorted Audio
Poor audio quality may result from a bad network connection. Ensure that your network
connection is capable of handling the correct bandwidth; LifeSize recommends that your network
connection be capable of at least 100Mbps (100-baseT) for best performance.
Also ensure the loudspeaker is not obscured or damaged at either end of the call. Do not stack
items on top of the phone.
Do not use any kind of liquid or aerosol cleaner on the phone. A soft, slightly damp cloth should
be sufficient to clean the top surface of the phone if necessary.
