Why does my phone display the
“No Service” message?
How to reset a user’s password?
The phone willl display the “No
Service” message if the SIP settings
have not been set up correctly. Check
that the SIP settings are correct in the
phone. If using the configuration files,
this could be a formatting or syntax
error. For example, when entering the
perameter “SIP line1 user
name:5551231234”, you cannot use
formatting symbols such as “-“ as in
“555-123-1234” to format the number or
the phone will not recognize it.

password in the Current

password to confirm the new
password.
