PERSON CALLED
Symptom: A person called with the voice
CAN'T HEAR CALLER
announcement to idle voice terminal procedure cannot
hear the caller.
Possible Cause
Misadministration of the
membrane button set.
Possible Solution
Check to see if the
membrane button set is
administered as a BIS/HFAI
voice terminal. If the set is
administered as a BIS/HFAI
set, the call is coming in on
voice 1 path while the
speaker is on voice 2 path.
That means the person called
hears a tone, but does not
hear the caller after lifting
the handset.
Because the set can handle
only one feature decide
whether the set should be
replaced by a BIS/HFAI set
or whether it should be
readministered to handle the
voice announcement to idle
voice terminal feature, and
administer accordingly.
Refer to “’Identifying Analog
Voice Terminal Type”’ on
page 3-41 for instructions.
