I cannot retrieve voicemail messages.
Your telephone has both a built-in answering system and voicemail indication.
They are independent features and each alerts you to new messages differently.
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.

the LCD language to English.
While the phone is on a call, press MENU, and then enter 364 to reset the
LCD language to English.
