Shared Line Appearance (SLA) and Shared Call Appearance (SCA)
A Shared Line is a service account or extension that is installed on a group of phones, such that if any phone is using
that
extension,
other
sharing
phones
will
be
notified.
There
can
be
multiple
simultaneous
calls
on
a
shared
line.
The
maximum
allowed
simultaneous
calls
on
a
shared
line
will
typically
be
fixed.
Each
call
on
a
shared
line
is
called
a
Share
Call
Appearance
(SCA)
and
is
sometimes
referred
to
as
a
Bridged
Line
Appearance
(BLA).
If
your
phone
has
a
shared
line
configured
as
one
of
the
services,
it
should
have
as
many
Call
Keys
defined
on
the
phone
as
are
bound
to
that
service.
SCAs
of
a
shared
line
are
ordered
with
an
index
1–n
as
SCA1,
SCA2,
SCA3,
...
SCAn,
where
n
is
the
maximum
number
of
calls
permitted
for
that
line.
On
the
OBi1000,
the
SCAs
are
assigned
sequentially
in
ascending
order
according
to
the
VLK
index
of
the
corresponding
Call
Key
bound
to
the
shared
line.
For
example,
suppose
a
shared
line
with
4
SCAs
is
configured
on
a
phone
with
VLK1,
VLK3,
VLK7,
and
VLK8
assigned
as
the
4
Call
Keys
bound
to
that
line,
then
the
calls
hosted
on
VLK1,
VLK3,
VLK7,
and
VLK8
are
SCA1,
SCA2,
SCA3,
and
SCA4,
respectively.

Intercom Calls
Intercom refers to a call with the following characteristics:
•
The called phone answers automatically, usually immediately without ringing and uses the speakerphone
or headset to answer the call. Typically the answering phone also plays a short beep to alert the called user
right after answering the call
•
The calling phone may support Push To Talk (PTT) such that the call ends as soon as the caller releases the
respective
PTT
key
on
the
calling
phone.
PTT
does
not
apply
to
the
called
phone
on
the
other
hand;
the
called
user
talks
and
ends
the
call
normally
just
like
any
other
call
When
an
intercom
call
is
received
and
answered,
all
other
current
calls
on
the
called
phone
will
be
interrupted
in
the
standard
way,
as
this
is
a
new
call
to
be
added
to
the
foreground.
With
the
OBi,
a
feature
key
may
be
assigned
the
function
“Auto
Answer
On/Off”
to
give
the
user
an
easy
way
to
disable
auto-‐answering
intercom
calls
in
case
they
do
not
want
to
be
interrupted.
If
Auto-‐Answer
is
turned
off,
the
intercom
call
will
be
presented
to
the
called
phone as a call and the phone will ring normally.
