IP 8000 Product Information 9
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 (from the Preferences - Audio menu).
Muffled reception may be caused by highly reverberant rooms. If you are experiencing poor
reception, add more sound absorbency to the room and speak in close proximity to the
phone.
Adjust the priority order for your audio codec (from the Preferences - Audio menu) 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 an IP 8000 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; ShoreTel 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.
Restoring Default Settings
You may need to reset the phone to its default state (from the Preferences - Maintenance -
Reset menu) to correct unknown problems you may be experiencing. If this reset fails, you
can also manually restore the phone to its default state by removing power, pressing and
holding the 7, 8, and 9 keys simultaneously until the Initial Configuration screen appears,
and then restoring power.
Press and hold the 7, 8, and 9 keys simultaneously, and then reapply power. Hold the keys
down until the Initial Configuration screen appears.
