service’s configuration can also be appropriately changed in order for it to monitor

the
telephone system

correctly
.

D.
Configure Customer’s Telephone System
CSTA
License
&
IP Routing

Overview

Since most
of the
required telephone system configuration is network
-
related, the
subsequent
diagram illustrates how the Akixi hosted service monit
ors the Customer’s
OpenScape Office
telephone system via a remote CSTA connection

using the following
hypothetical
telephone system
& router IP address configuration
:

Customer’s
Public Router IP Address:

1.1.1.1

Customer’s
Internal Router IP Address:

192.168.1.254

Siemens
Main LAN Interface:

192.168.1.2
00




Configure Telephone System For Remote CSTA Connection

Enable the telephone system to accept CSTA connections from the Akixi Hosted Service as
follows:

1.

Configure Default Gateway

Ensure that the Customer’s internal router IP address (192.168.1.254 in the example
above) is set as the
telephone system’s
default gateway under “
Exp
e
rt Mode



Routing


IP Routing


Default Router”

within the telephone system’s web
administration tool.

2.

Enable Routing Entry For Akixi Hosted Service

Create
a routing table entry for the
assigned
IP address of the Akixi Hosted Service

for the corresponding Customer
(
a “

x
.

.
x” address provided to you in a separate e
-
mail
), specifically setting its route to

the
internal
IP address
of the Customer’s
router
.

This is set under “
Exp
e
rt Mode



Routing


IP Routing


Static Routes”

within the
telephone system’s web administration tool.

A subnet mask of 255.255.255.255
should be used for the routing entry.

Other Re
quired Telephone Syste
m

Complete the following non
-
network related telephone system configuration:



Ensure that
2
free
(unused)
CSTA application license
s

are
available on the telephone
system.

Two available licenses are required because some OpenScape systems appear
to have an issue relinquishing a previously used license when the Customer’s router is
restarted.

The specific license name is
"OpenScape Office LX/MX CSTA Application" license
, whi
ch
corresponds to Siemens specific
part code L30250
-
U622
-
B446

(
or
L30250
-
U622
-
B4
68

in
newer product catalogues)
.

The system’s currently installed licenses can be viewed under “License Management


License Information” within the telephone system’s web administration tool.

It is important
that the “used licenses” column shows (unused) free licenses, e.g. “0 of 1”, “1 of 2”, “3 of
4” is OK, but not “1 of 1”, “2 of 2”, “4 of 3”, etc.



For security purp
oses unless specifically required, restrict (prohibit) all stations from
making international & premium rate calls.

E.
Configure Customer’s Internet Router

NAT / Port Redirection

Arrange for
the
Customer’s internet router / firewall to have a NAT / port re
direction entry
created for TCP port
8800
, which maps to the internal IP address of the
telephone system’s

main LAN interface.

This basically
maps
TCP port
8800
on the public side of the router
to the
system’s
CPU
’s

IP address

and allow
s

inbound access for

the CSTA protocol
.

For example, using the previously specified hypothetical
telephone system

& router IP
address configuration:

Example NAT / Port Redirection Mapping Entry

Protocol:

TCP

Public / WAN IP Address:

Any

or 1.1.1.1

Public Port:

8800

Mapped / Private IP Address
:

192.168.1.200

Private Port
:

8800


Firewall
Filter
Rules

Arrange for
the
Customer’s internet router / firewall to have
the appropriate firewall rules to
specifically only allow the Akixi Hosted Service inbound access over TCP
8800
.

Typically on most firewall configurations, this can be achieved using two individual firewall
rules in a chain: the first that allows inbound access on TCP port
8800
from the Akixi Hosted
Service, and
then
a second

rule
, which blocks any other IP add
ress
es

accessing
TCP
port
8800
.

For example:

Example
Firewall Chain Entry 1

Action:

Pass/Allow Immediately, Then Exit
Rules
Chain

Direction:

Inbound (WAN/Public
