Determine the number associated with the
telephone. Dial that telephone number from a
“wired” telephone. If you hear busy tone, the
base unit is not communicating with the
communications system. Perform the
following steps:
• Check the power.
• Verify that the telephone cord is connected
to the base unit.
• Verify that the ID of the handset matches
the ID of the base unit. To determine the ID
of the handset, remove the battery cover
and look at the ID on the bottom of the
handset. (A bar code appears below the
ID.) To determine the ID of the base unit,
look at the ID on the bottom of the base
unit.
• Verify that the installation guidelines have
been followed, especially for systems
where there are more than three Avaya

Echo during
conversation Depending on the environment from which
you are calling, such as a noisy area, a caller
may experience echo if the volume control of
the handset is set too high. Try lowering the
volume on your handset. If that does not help,
contact your authorized dealer.
