Translating voice calls between digital for the Internet and analogue for
telephone systems is a challenging task, and that is the task that VoIP
gateways perform by switching the calls between analogue and digital.
Directing calls to specific users is also a function performed by the
gateways. And they are able to translate between different VoIP
protocols. This protocol translation is important because it enables
different VoIP systems to talk to each other. Because of all of these
benefits it is easy to see why VoIP gateways are highly recommended for
any VoIP service.

Since VoIP technology is becoming ever more popular, VoIP gateway
customers have a lot of products available. Mediatrex Telecom and Cisco
System are two examples of manufacturers that produce leading VoIP
gateway systems.

VoIP gateways can either be hardware or software based. The hardware
gateways tend to cost more than software gateways and can be purchased as
a stand alone box. They tend to be viewed as more reliable and do not
consume computer power.

Buyers of VoIP gateways can select from products that offer numerous
phone, fax machine, PBX and STN support capabilities.

The basic VoIP gateways at the lower end of the cost graph comes equipped
with a firewall, a router, and a telephone jack, and can be purchased for
a few hundred dollars. This type of device can offer three ports: one for
a telephone jack, one for a broadband modem or router and one for a
computer or network device. These low end VoIP gateways targets the home
user and small business owner.

At the mid range of gateways, additional functionality such as signal
encryption and voice compression is offered to ensure security and
efficient bandwidth usage.
At the higher end of the market are VoIP gateways that cost several
thousand dollars and are widely used by telephone carriers and large
companies. These systems have sophisticated functionality such as
interactive voice response systems for automated voice response
functions, and they can carry thousands of simultaneous telephone
conversations. They also offer other functions like conference calling
and call recording.

There are new features and functions for VoIP gateways being built all of
the time, such as support for emerging VoIP standards and faster
translations. Many of these improvements are software based and therefore
can be sent to customers very quickly and cheaper in the form of a
software upgrade.

One can expect to   see many more enhancements and improvements before VoIP
and VoIP gateways   can be considered a matured and saturated market. The
end user benefits   from these improvements because quality and range of
services increase   while overall call costs tend to be constantly driven
downwards.
