Problem
Possible Solution(s)
Why does my phone display
the “No Service” message?
The phone displays the “No Service” message if the SIP
settings have not been set up correctly. You can still use the
phone but it is not registered with the Registrar. For more
information about registering your phone, see your system
administrator.
How do I restart the IP
phone?
This setting is in the Options list. See Restart Phone.
