THE
EVOLUTION OF VOIP
VoIP
technology was introduced to the mass audience in the year 2004.We at Welcome
Telecom gives early adopters, with a
good concept and under your budget, were willing to overlook obvious quality
issues. Earlier people had to lead with call drops while using cell phones but
by using VOIP these problems will be avoided. While VoIP marked a technological
leap forward for network management and lower budget, audio quality took
several steps back.
However,
same way the network and technical advances have widely overcome cell phone
problems and high definition has provided a new standard for television, VoIP
quality for home and business phones is much better than the earlier days.
WHY VOIP IS HERE TO STAY
IP can take the voice
communication to the next level. While there are many ways to save cost and many
features that come with VoIP
systems, the main advantage is the voice quality. VoIP call quality has not
only matched Public-Switched Telephone Network (PSTN) quality but it gives
companies to far surpass PSTN with wideband audio. Voice is the most crucial
component of any communication system because it creates a personal bonding
between people. The ability of VOIP is crisp and clear voice which is very
important in todays world and also while contacting with international clients.
VOIP SYSTEM COMPONENTS
A VoIP system is also referred to
as IP PBX. Although the specifications of each system are different from one
another, there are some basic elements in each VoIP network:
• Endpoint. It is used to send
and receive calls.
• Proxy Server. VoIP connections
are controlled through endpoint registration, authentication, and call setup
and tear down.
• Message protocols. The message
protocol used to communicate with the proxy server. It is used for
registration, call setup and tear down, and also helps determine which CODEC is
used for the call. SIP, H.323, SCCP, and MGCP are all message protocols..
• CODEC. A system used to encode
and decode the audio into RTP packets. The CODEC always have a big impact on
audio quality because it specifies the audio bandwidth.
• Session border controller
(SBC).
• Media gateway. It provides
translation between VoIP phones and the phones which are not on the network
such as external landlines, PTSN, and cell phones.
• IP Network. Carries network and
VoIP data. Both the corporate intranet and the public Internet is included. Extra
things may come into play, such as a DHCP server to assign an IP address and a
DNS server to assign and manage domain names.
CONCLUSION
VoIP will soon become the standard in
corporate communication, with 80% companies will take up this services by next
year. Because VoIP supports wideband audio that is more than double than the
PSTN, users can hear more natural sound and increased intelligibility. The
benefits of VoIP naturally extend into the conference room. Users always expect
high-level sound quality without clipping or frustrating ambient noise something
that regular VoIP speakerphones can’t provide.
