PROBLEM CORRECTIVE ACTION
The telephone port
won’t work or the
telephone lacks a
dial tone.
Check the telephone connections and telephone wire.
Make sure you have the
VoIP SIP Settings screen properly configured.
I can access the
Internet, but
cannot make VoIP
calls.
Make sure you have the VoIP SIP Settings screen properly configured.
The VoIP LED should come on. Make sure that your telephone is connected to
the LINE port.
You can also check the VoIP status in the Status screen.
If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you
cannot make a call using speed dial, there may be something wrong with the SIP
server. Contact your VoIP service provider.
