What You Need To
Know About VoIp
VoIP changes the entire viewpoint
of people regarding long distance calls.
In this method, the audio analog signals
are being transformed to digital data
that are transmitted via the Internet.
VoIP also called as Voice over
Internet Protocol, Voice over Broadband,
Internet Telephony, IP Telephony,
Broadband Phone, and Broadband Telephony
refers to the voice routing
conversations via Internet or any other
network that are IP-based. VoIP
Protocols or Voice over IP Protocols is
used for carrying voice signals over IP
networks.
It is the result of the Network Voice
Protocol experiments invented on 1973
for ARPANET providers. One network is
used for carrying data and voice
especially for users with underutilized
network. This allows saving significant
amount of money because phone calls
using VoIP on different providers are
usually free. However, calling from VoIP
to PSTN will charge the person using the
VoIP.
The PSTN to VoIP services are Direct
Inward Dialing (DID) and access numbers.
In DID, the callers is directly
connected to the user of VoIP but in
access numbers, the callers is required
to enter the VoIP user's extension
number. A monthly fee is charged on DID
while access numbers is free of charge
for VoIP users and local calls for
callers.
VoIP changes the entire viewpoint of
people regarding long distance calls. In
this method, the audio analog signals
are being transformed to digital data
that are transmitted via the Internet.
The standard connection of the internet
becomes a way in placing phone calls for
free. Utilizing VoIP software for free
is the practical way of saving money and
bypassing phone companies and its entire
charges.
VoIP is an innovative technology with an
ability to rework the phone systems
completely all over the world. VoIP is a
one way phone call but offers different
VoIP services commonly used today.
1. ATA is the most common and simplest
way of service using the Analog
Telephone Adaptor device which converts
analog signals to digital signals. It
allows standard phone connection to your
computer or internet connection for VoIP
use. The converted analog signals are
transmitted on the internet.
2. IP phones are specialized phones
resembling normal phones with cradle,
buttons, and handset. The only
difference is that a phone connector
(RJ-11) is used by standard phones while
an Ethernet connector (RJ-45) is used by
IP phones. IP phones are directly
connected to the router with all the
necessary software and hardware in
handling IP calls. IP phones that are
Wi-Fi will also soon be available. VoIp
calls can be done at all Wi-Fi hotspot.
3. Computer-to-computer is the easiest
method of using VoIP. Calling long
distance is free. There are a few
companies which offer free or very cheap
software to make use of this method. The
user only needs a microphone, sound
card, speakers, Internet connection (via
DSL modem or cable) and the software.
However, the users need to pay the ISP
monthly fee.
Trying VoIP is not a problem since there
are plenty of VoIP softwares in the
Internet for free. All you need to do is
to download and setup it at about 3 to 5
minutes. To test it, you could invite a
friend to do the same and check it if
it's really working. This is a good
opportunity.
VoIP are used by most phone companies in
streamlining their networks. They are
routing phone calls via IP getaway and
circuit switch reducing the bandwidth
they are using for long hauls. Once the
getaway received the calls, the other
side will route, reassemble, and
decompress it locally in a circuit
switch.
This will take time but the current
networks of circuit-switched are
replaced by a technology called
packet-switching. The data networks just
retrieve and send data whenever the user
needs it. It does not allow routing of
data via dedicated line instead it
allows flowing of data packets through
chaotic networks provided with numerous
possible paths. It simply opens brief
connections to send the packets (small
piece of data) from systems to systems.
This method is very efficient because
packets flow through the cheapest and
least congested lines while still
allowing both communicating computers to
accept information.
IP technology really makes sense both in
infrastructure and economics
requirements. More businesses are
installing the VoIP systems and this
technology will grow more in popularity
making its way for home use. VoIP is a
breakthrough in improving traditional
phone systems to become very efficient
and a reliable way of communication.
