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.
If you are using the speakerphone, turn off the
speakerphone and try using the handset’s
built-in microphone and ear piece.
No dial tone. Move back within the system range limit (for
example, move closer to the base unit or a
repeater.) Consider installing a repeater if you
experience this condition frequently.
Confirm that the telephone has been
administered properly. See the Avaya 3920
Wireless Telephone Planning and Installation
Guide for more information.
