VoIP equipment manufacturers face the challenge of designing
products that will work with a variety of different standards.
Different VoIP protocols such as H.323, SIP and MGCP exist for
the transmission of voice and multimedia over the Internet, and
then there are the different telephony signaling standards such
as ISDN PRI/BRI, T1/E1, FXS/FXO and Ethernet network interfaces.
At Patton Electronics, we have designed a range of
VoIP equipment that
will work with just about any interface and telephone signaling
system now in existence.
A key piece of equipment is the device that connects the IP
network to the PBX system. Entry-level systems may require only
a gateway at each location to encode and decode the voice signal
for the PBX, while more complex systems would call for a router
or IP-PBX to replace an existing analog PBX. Our range of
SmartNode gateways, routers and SmartLink handsets
and IP-PBX devices are able to meet the requirements of any
system from a SOHO installation to a fully fledged ToIP, or
The H.323 VoIP standard is most widely used but lacks the
features necessary to completely replace existing telephone
systems. Because it offers only basic telephony functions,
handsets and other devices need more complex and expensive
circuitry. The MGCP, or Media Gateway Control Protocol, was
created to simplify standards and reduce the cost of these
devices. SIP, or Session Initiation Protocol (recommended by the
Internet Engineering Taskforce), is another standard now gaining
a strong following.
VoIP Equipment in the Future
Given the range of possible applications and all the different
standards, flexibility is the key to a successful VoIP product
design. Evolving standards require that equipment can be updated
easily. At Patton Electronics, our range of VoIP products meet
this challenge and our free software updates ensure the future
of an investment in our equipment.
