VoIPBox DSL / VoIPBox BRI – version:20.0.005
This chapter contains the safety and security precautions. Please be sure and take
time to read this section to ensure your personal safety and proper operation of your
gateway. To avoid personal injury or damage to the system, please follow all safety
instructions before you begin working on your gateway. VoIPBoxes are CE certified
and fulfill all relevant security requirements. The manufacturer assumes no liability
for consequential damages or for damages resulting from unauthorized changes.
2.1 Safety Measures
Danger of electric shock - the power supplies run on 230 V. Do not open the VoIPBox or its
power supply.
Make sure to install the VoIPBox near the power source and that the power source is easily
accessible.
Bear in mind that telephone and WAN lines are also energized and can cause electric shocks.
Be sure to respect country-specific regulations, standards or guidelines for accident preven-
tion.
2.2 Power Supply
The included power supply is to be used exclusively for operation of your VoIPBox.

VoIPBox DSL / VoIPBox BRI – version:20.0.005
2.2.3 Instructions for Use
Plug the power supply directly into the outlet. The power supply provides safety-low voltage
with limited capacity for your VoIPBox.
The devices are designed for constant use in dry, indoor locations. However, we recommend
that you unplug them if you do not intend to use them for an extended amount of time. Make
sure the power outlet is easily accessible at all times.
2.2.4 Safety Precautions
Make sure you follow these safety precautions:
Electrical devices may not be used by individuals who are not aware of the dangers of
electricity and/or the incorrect use thereof.
Make sure you use only the correct input voltage.
Make sure the installation site is sufficiently ventilated.
Use the device only in dry, indoor locations, and protect it from humidity.
Do not subject the device to direct sunlight.
Unplug the device if you do not intend to use it for an extended amount of time.
Hold the device by its housing when you unplug it. Wall outlets can become
mechanically overloaded; do not pull on the cord.
The room temperature may not exceed 35°C.
Do not use the device if it is damaged or if there are signs of misfunction. In this case,
send it to TELES Service or dispose of it properly (not with household waste).
2.3 Jacks
The jacks on the VoIPBox have fulfilled the requirements of the SELV safety standard.
2.4 EMC Protection
2.5 System Security
This section describes all points crucial to the VoIPBox’s system security.
The VoIPBox’s location must support normal operation according to EN ETS 300 386. Be sure
to select the location with the following conditions in mind:
Use only the power supply included in the package contents of your VoIPBox.
i
i
Use shielded cables.
Do not remove any housing components. They provide EMC protection.
Location: Make sure you install the system in a clean, dry, dust-free location. If possible, use
an air-conditioned site. The site must be free of strong electrical or magnetic fields, which
cause disrupted signals and, in extreme cases, system failure.

2.5.1 Servicing the VoIPBox
Regular servicing ensures that your VoIPBox runs trouble-free. Servicing also includes looking
after the room in which the system is set up. Ensure that the air-conditioning and its filter
system are regularly checked and that the premises are cleaned on a regular basis.
2.5.2 Protecting the Operating System
Changing configuration data may lead to malfunctions and/or misrouting, as well as possible
consequential damage. Make changes at your own risk. TELES is not liable for any possible
damage resulting from or in relation to such changes. Please thoroughly check any changes
you or a third party have made to your configuration!
To make changes in or perform tests on the database, make sure your flash disk contains
enough storage space. Downloading the log files and deleting them from the VoIPBox on a
regular basis will ensure your VoIPBox’s reliability.
Be careful when deleting files that you do not delete any files necessary for system opera-
tion.To check storage space and/or delete files, use GATE Manager. For more information see
the document TELES.GATE Manager. All files with the extension *.log can be deleted. To
save files before deleting them, use the Receive File option in GATE Manager.
2.6 CDR Files
Call Detail Records are intended for analysis of the VoIPBox’s activity only. They are not de-
signed to be used for billing purposes, as it may occur that the times they record are not exact.
2.7 Network Security
Every day, hackers develop new ways to break into systems through the Internet. While TELES
takes great care to ensure the security of its systems, any system with access through the In-
ternet is only as secure as its user makes it. Therefore, to avoid unwanted security breaches
and resulting system malfunctions, you must take the following steps to secure your VoIPBox
if you connect it to the Internet:
Use the installed firewall.
Access to the VoIPBox via GATE Manager must be password protected. Do not use
obvious passwords (anything from sesame to your mother-in-laws maiden name). Bear
in mind: the password that is easiest to remember is also likely to be easiest to crack.
Temperature: The site must maintain a temperature between 0 and 35°C. Be sure to guard
against temperature fluctuations. Resulting condensation can cause short circuiting. The hu-
midity level may not exceed 80%.
To avoid overheating the system, make sure the site provides adequate ventilation.
Power: The site must contain a central emergency switch for the entire power source.
The site’s fuses must be calculated to provide adequate system security. The electrical facilities
must comply with applicable regulations.
The operating voltage and frequency may not exceed or fall below what is stated on the label.
!
!
Inaccuracies in the generation of CDRs may occur for active connections if traffic is flowing on
the system while modifications in configuration or routing files are activated.

VoIPBox DSL / VoIPBox BRI – version:20.0.005
This chapter gives you an overview over the VoIPBox DSL / VoIPBox BRI. All types of
VoIPBox DSL / VoIPBox BRI are listed, also the list of features and two implementa-
tion scenarios.
The VoIPBox BRI is a media converter that facilitates the connection of ISDN service equip-
ment with a voice over IP (VoIP) network. It converts line-based transmission on the ISDN side
to packet-based transmission in the IP network and vice versa. Incoming traffic arrives at one
VoIPBox, which routes the calls accordingly, depending on the call’s destination and at-
tributes. The VoIPBox is available with two, four, or eight BRI ports.
The VoIPBox BRI Family includes the following variations:
VoIP Box DSL 2
VoIP Box DSL 4
VoIP Box DSL 8
VoIPBox BRI 2
VoIPBox BRI 4

3.2 Implementation scenarios
These are the most commonly used implementation scenarios.
VoIP gateway
The VoIPBox’s sophisticated routing algorithms allow VoIP communication via SIP server and/
or gatekeeper (H.323), as well as multi-destination operation without a SIP Server or gate-
keeper. Various voice codecs ensure universal connection to different VoIP destinations. Fax
transmission occurs via T.38 or fallback to G.711a.

4.4 Installation Requirements
Before installing your VoIPBox, make sure you have the following connections in place:
ISDN BRI connection to PBX and/or to the PSTN
Power
4.4.1 ISDN Wiring
The TE ports connect to the PSTN and the NT ports connect to the PBX. Only the first port
ISDN1 can be configured as a TE port. It is also possible to configure port ISDN1 as NT to con-
nect a telephone or PBX.
Figure 4.3 shows the standard pin assignment for TE and NT modes. You must change the
pin assignment if it differs on the connected equipment
