Completing the VoIP settings
After the entries have been completed, the handset reverts to idle status.
If all the settings are correct and if the phone can establish a connection to the VoIP server,
then the internal name of the handset will be displayed (example):
You can now use your phone to make calls via the fixed line network and the Internet.
Callers can reach you on your fixed line number and your VoIP number.
No connection to the Internet/VoIP server
If one of the following messages is displayed instead of the internal name after the con-
nection assistant is closed, errors have occurred:
u Server not accessible!
u Provider registration failed!
Below you will find possible causes and measures you can take.
Please note:
– To ensure that you can always be reached via the Internet, the router must be permanently con-
nected to the Internet.
– If you try to make a call via a VoIP connection that is not configured correctly, the following VoIP
status message will appear on the display: IP configuration error: xxx or VoIP config.error: xxx (xxx =
VoIP status code). The various status codes and their respective meanings can be found on
page 167.
