With
these
telephone
door
entry
systems,
you
don't
tie
yourself
up
with
proprietary
appliances
(i.e.
special
wall
speakers)
which
limit
your
decor-matching
choices,
make
you
dependent
on
specific
brands,
and
will
never
be
as
cost-effective
as
standard
phones.
Cost-effectively
use
your
phones
for
both
normal
phone
calls
and
door
answering
intercom.
You
can
answer
a
door
call
from
any
phone
in
your
home
and
all
your
phones
will
ring
on
a
door
call
to
announce
your
guest.
Phones
will
ring
in
a
very
distinctive
way
so
you
know
it's
a
door
call
and
not
a
regular
phone
call.
While
you
are
on
a
phone
call,
you
can
still
receive
door
call
warnings
with
call
waiting.
This
call
waiting
tone
is
generated
by
the
door
entry
system
itself
and
is
distinct
from
call
waiting
provided
by
the
local
phone
company. These
door
entry
systems
are
completely
transparent
to
all
other
line
services
provided
by
the
local
phone
company,
i.e.
caller
ID
and
the
like.
Note
that
the
Ultimatoll
door
entry
systems
will
still
operate
properly
in
the
event
that
the
dial
tone
service
becomes
unavailable
on
the
phone
line
(discontinued
phone
service
or
damaged
phone
line).
Door
calls
will
still
ring
the
phones
with
availability
of
intercom
from
any
handset.
Get
convenience,
comfort
and
security
with
a
great
door-to-phone
answering
system!
