Troubleshooting
My telephone does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features from your telephone
service provider. Caller ID feature works only if both you and the caller are in
areas offering caller ID service, and if both telephone service providers use
compatible equipment.
New voicemail and show and I don’t know why.
If New voicemail and appear, then your telephone has received a signal
from your telephone service provider that you have a voicemail message waiting
for you to retrieve from them. Contact your telephone service provider for more
information on how to access your voicemail.
I cannot retrieve voicemail messages.
If you subscribe to voicemail service from your telephone service provider,
contact your telephone service provider for more information on how to access
your voicemail.
I subscribe to a nontraditional telephone service that uses my computer to
establish connections, and my telephone doesn’t work.
Make sure your computer is powered on.
Make sure your Internet connection is working properly.
Make sure that the software is installed and running for your nontraditional
telephone service.
Make sure to plug your USB telephone adapter into a dedicated USB port on
your computer. Do not plug into a multiple port USB hub (USB splitter) that is
not powered.
In a few rare instances, the USB port on your computer may not have enough
power. In these instances, try using a USB hub with its own external power supply.
If you are using a firewall, it may prevent access to your nontraditional telephone
service provider. Contact your service provider for more information.
I accidentally changed the LCD language to French or Spanish, and I don’t
know how to change it back to English.
While the phone is not in use, press MENU, then enter 364 to reset the
LCD language to English.
While the phone is on a call, press
MENU, then enter 364 to reset the
LCD language to English. Then the call ends.
