That
shared
phone
line
will
continue
to
work
in
your
existing
phone
system
as
usual
for
receiving
incoming
phone
calls
and
for
making
outgoing
phone
calls.
However,
it
will
also
now
ring
on
your
phones
when
there
is
a
door
entry
call
from
your
outdoors
doorphone
and
will
support
intercom
conversation
with
the
doorphone
as
well.
The
door
entry
system
will
not
affect
any
service
available
on
your
phone
line
from
the
local
phone
company,
like
caller
ID,
call
waiting,
etc.,
except
for
internet.
If
you
have
one
single
phone
line
and
need
a
door
entry
system
that
is
also
100%
compatible
with
internet
use
of
the
line,
see
the
PhoneBell
Q-10
system.
With
a
wireless
phone
system,
the
door
entry
Controller
need
only
be
connected
to
the
base
station
of
the
wireless
system.
The
Controller
will
feed
the
phone
line
to
that
base
station
from
its
remote
location
at
the
home
Telephone
Interface
Block.
