Numbering
Plan
The
default
numbering
plan,
which
is
the
telephone
extension
numbers
is
set
to
101
~
125,
but
can
be
changed
to
2
digits
10,
11,
12,
etc.
or
4
digits
1001,
1002,
1003,
etc.
If
you
are
using
X
‐
2020
telephones
and
you
are
satisfied
with
this
numbering
plan,
you
do
not
have
to
enter
anything
at
this
time.
The
X
‐
2020
telephones
will
automatically
authenticate
using
an
extension
number
(101,
102,
103,
104,
etc.)
as
the
phone
number
and
the
same
extension
number
twice
(101101,
102102,
103103,
104104
etc.)
as
the
password.
In
addition,
the
phones
will
connect
to
a
new
or
existing
network
using
DHCP,
making
them
truly
plug
and
play.
You
can
also
change
the
passwords
by
entering
the
extension
number
and
password
in
the
Extension
Registration
area.
Note:
If
you
are
using
off
‐
site
or
remote
telephones
it
is
a
good
idea
to
have
them
authenticate
with
a
specific
extension
number.
This
is
because
the
WAN
port
authenticates
first,
which
may
cause
the
telephone
to
authenticate
using
a
different
extension
number.
At
default,
all
authenticated
extensions
numbered
101~124
will
ring
when
a
call
rings
into
the
system.
