of
defined

known
as

The

are

There
are
many
operations
that
may
be
applied
to
a
call
-­‐
for
example,
holding,
resuming
or
ending
a
call
are
commonly
used
operations.
The
options
to
manipulate
a
call
are
typically
presented
to
the
user
as
soft
key
options,
while
the
most
frequently
used
call
operations
can
also
be
mapped
to
a
feature
key
-­‐
such
as
the
Hold
and
Transfer
functions.
Soft
key
options
are
call
state
sensitive,
only
the
options
that
are
applicable
to
the
call
at
its
current
state
are
shown
and
as
the
call
transitions
from
one
state
to
another,
the
soft
key
options
on
the
screen
will
be
updated
accordingly.
This
will
be
discussed
further
in
the
“Calls
App” section.
As
detailed
in
the
section
titled
“Call
Keys”,
each
call
on
the
phone
must
be
assigned
to
a
call
key
and
each
call
key
has
its
own
VLKW
on
the
screen
that
is
displayed
next
to
the
line
key.
To
help
the
user
identify
the
current
state
of
a
call,
each
call
state
is
represented
by
a
distinct
icon
that
is
shown
in
the
respective
VLKW.
Furthermore,
the
LED
of
each
call
key
stays
steady
or
blinks
with
a
certain
pattern,
indicating
the
current
call
state.
Making Basic Calls

Lifting
the
handset
from
the
cradle
will
start
the
dial
tone
and
display
the
Dial
Dialog
on
the
screen.
The
following
figure
shows
a
dial
dialog
ready
for
the
user
to
enter
a
number.
