Analogue gateways are available with two different port configurations
FXS or
FXO depending on whether the gateway is used on a stand alone basis with
analogue phones directly connected or integrated into an office
telephone system. In essence, an FXS VoIP port cannot connect
directly to the public telephone network (PSTN) but can be used with a
standard analogue telephone or an analogue telephone system to make VoIP calls. An FXO port does connect
directly to the PSTN allowing calls to be
made via the PSTN and also allowing incoming calls to be diverted via
the VoIP service. This is particularly useful in enabling your staff to
make international calls from their mobile/cell phones at our excellent
call rates. Learn how to maximise the benefits of a VoIP gateway
with the flexibility of both
FXS and
FXO ports.
Stand alone Voice over IP gateway configurations are suitable for small offices with no
existing office telephone system, callshops or where the number of users
of the VoIP service will be very small.
Installation of a stand alone environment is simple once the
gateway has been correctly configured and a VoIP account is obtained
with a VoIP provider such as EWC. Just by plugging analogue
phones directly into the VoIP gateway and connecting to your broadband
the business can make and receive calls via VoIP. Since any analogue telephone can be connected to the
gateways it is possible to connect your Fax machine and even use
wireless
phones for even great flexibility. VoIP gateways are programmable
using dial plans, allowing you to include speed dialling, follow on for
incoming calls if the first port is engaged and many other functions
that make communications easier and
more cost effective for
a small business. Using Voice over IP from EWC for incoming calls also
provides free voicemail and since its VoIP its possible to pick the
messages up anywhere in the world through the internet.

For connection
to an existing analogue office system, the best solution is to use an
FXS VoIP
gateway with a PBX. In this instance the PBX needs to be reprogrammed so
that the appropriate calls can be routed via the gateway. For instance,
if only the international calls were to be routed via VoIP in most
countries the PBX would route all numbers starting 00 through the VoIP
gateway with the remainder still going through the local phone company.
If all calls were to be sent via VoIP the PBX would be programmed so
that only emergency calls went across the local telephone network. The
disadvantage of this approach is that programming is required on the
existing office telephone system. This is
offset by the major advantage that
the office staff continue to access an outside line in the same
manner as they have always done, thus ensuring the maximum usage of the
VoIP service.

For ultimate flexibility it is possible to use a combined FXS and
FXO VoIP Gateway.
EWC can also
provide local numbers and
toll free numbers
in many countries, with the calls being directed to the VoIP gateway. With two VoIP gateways in separate locations it is possible to
make free calls between the locations simply by dialling a speed dial.
