What is VoIP Voice Over Internet
Protocol?
Make all the
long distance phone calls you want for one low price! Many broadband Internet
providers are touting new services to make long distance bills a thing of the
past. Companies are foregoing traditional telephony service and opting to go
with newer services that use network technologies to provide telephone service.
How are these things possible?
Voice Over Internet Protocol (VoIP) is a new technology that uses broadband
Internet and/or network lines to transmit real-time voice information. This
technology has the potential for completely changing the way phone calls are
made and making phone companies a thing of the past.
To make a
phone call on the Internet, several things must happen. On the sending side,
analog voice signals are digitized, compressed, divided into packets and
transmitted over network lines. On the receiving end, the signals are
recombined, uncompressed and converted back into audio. Because the voice
signals are digital, they can be transmitted just like any other data packets
on a network. The major difference between these voice packets and regular
data packets is that for VioP to be effective, the signals must be delivered in
a timely, reliable manner. VioP can be relatively inexpensive to implement, although
costs rise as the complexity of the system increases. Because many companies
already possess the infrastructure necessary to implement VoIP, more and more
of them are opting to forego traditional fone service. Cisco's CEO John
Chambers predicts that enterprise networks will accelerate their adoption of
Voice over IP technology.
There are currently several problems with this technology. If the computer or
network lines fail, then telephone service is interrupted. While the stability
of computer hardware, operating systems and network infrastructure has improved
significantly in the last decade, crashes still occur. The "up" time of these
systems is still significantly less than with traditional phone systems--which
often continue to function even during power outages. Another issue is that
tracking the origin of a call is difficult because the signals are transmitted over the
Internet. This is especially important to emergency responders to
911 calls. Caller ID service may not function either.
Additionally, devices
that make calls using phone lines, such as fax machines, cable TV boxes, etc.
may not function properly. Law enforcement officials may have difficulty
wiretapping phone lines that use VioP technology. Finally, the quality of
VioP
service is lower than that of a traditional phone system. Since the
information is transmitted over network lines, it is subject to the same issues
that other data streams experience including delays, packet loss and bandwidth
availability. Thus VioP phone calls may break up, hesitate, or cause words to
be dropped. All of these issues are being addressed and their significance
should be eliminated over time.
How Viop Phones Work
Long distance phone calls
will never be the same again thanks to Voice over Internet
Protocol (VoIP). The basic premise for this technology is to
convert analog audio signals into digital data for transmission
over the Internet, a technique which allows you to make your phone
calls over the internet.
The way viop works is pretty straight forward. Whereas the
traditional circuit switched technology reserves a dedicated path
from a caller to the receiver for the entire duration of the
conversation, viop converts the voices into data for transmission
over data networks. At the receiving end, the data is once again
converted back into audio.
The implication of this process is that a regular Internet
connection is all one needs to make absolutely free phone calls.
In using free viop software for Internet phone calls, the role of
the telephone company and consequently its charges are completely
eliminated.
This path breaking viop technology is poised to redefine the very
method the world's phone systems use. Major players in the viop
world, like Vonage, are already making their presence felt having
been on a steady growth for some time. Leading traditional
carriers like AT&T are already in the process of incorporating
this revolutionary new technology in markets across the US.
Simultaneously, regulatory agencies including the FCC are taking a
long hard look at viop to harness the technology into a more
secure format.
Among the multiple advantages attributed to viop technology,
include the use of the same lines for both data and voice
transmissions. With one network, both installation and maintenance
expenses are minimized. Compression technology makes it possible
for multiple calls, as many as eight, on the same lines as opposed
to the circuit-switch systems. Neither is there any compromise on
sound clarity.
With viop it is also possible for various devices to be
inter-linked, thereby enabling added incentives like PC-Telephony.
Integrating the phone system to a customer database provides ideal
support for customer relationship management or CRM.
Phone calls using viop are not subject to toll charges. When both
sides have high-speed Internet access and viop phones, distance
charges don't apply no matter how long the call duration or
distance may be. The possibilities in terms of businesses and
consumers to save on costs are therefore staggering. What's more
viop can also be utilized in setting up an independent private
interoffice networks for main to satellite office communications. |
