No Service - Aastra 9143i User Manual

No Service

When the phone is not properly connected to the network, or the account has not been
configured by the Network Administrator, the "No Service" or "Network Disconnected" prompt
appears on the display and the telephone status light turns ON. The phone also displays the
default time and date of 12:00am Jan. 1st, 2000. Check that the cables are tightly connected to
the phone and to the wall jack. The phone should automatically detect when the connection is
reconnected and display the "Network Connected" prompt temporarily.
If changes have been made to your phone settings, you may need to restart your phone. For more
information on restarting your phone, see "Restarting Your Phone" on page 43.
For more information about connecting your phone, refer to the Aastra 9143i Installation Guide.
Check with your System Administrator for assistance.
