• If there is no dial tone, make sure that the telephone line
cord from the telephone is plugged into the appropriate
port on the Cisco ATA. Make sure that your Cisco ATA is
properly registered on your Call Control system. Test
another phone; if this phone does not work either, there
may be a problem with the current configuration or with
the Cisco ATA.
• A busy tone indicates that the party you called is not

indicates that you dialed an invalid number.

the MAC address listed on the product label or given by the
voice prompt.
