Internet telephony refers to communications services
including voice, facsimile, and/or voice-messaging
applications that are transported via the Internet, rather than the
public switched telephone network (PSTN). The basic steps involved in
originating an Internet telephone call are conversion of the analog
voice signal to digital format and compression/translation of the signal
into Internet protocol (IP) packets for transmission
over the Internet; the process is reversed at the receiving end. This
technology is growing quickly as IT decision makers recognize its value
VoIP has one compelling advantage - lower cost.
Traditional phone calls work by allocating an entire phone line to each
call. With VoIP, voice data is compressed and transmitted over a computer
network. This means VoIP uses up to 90% less bandwidth than a traditional
phone call and is consequently more cost effective and more efficient.
Phone companies are already using the technology to carry
international calls. Currently 6% of international traffic is internet-based.
According to a recent research report this will be up to 75% by 2007
(Frost & Sullivan). In fact if you use a cheap, long distance telephone
service, you're probably already using IP telephony without knowing
VoIP is helping the phone companies save money, and by introducing a
VoIP phone system on your own computer networks, you could do so too.
For any business, the immediate benefits can be:
Cheaper external calls. You can make
long-distance and international calls for the price of a local call.
Free internal calls to all parts of your company that share a computer
network. With a Virtual Private Network (VPN) in place you can speak
to connected colleagues at different branches or on the road for free.
Cheaper calls are not the only advantage.
With VoIP on your network you no longer need separate cabling for your
Scalability. Traditional PBX (Private Branch Exchange) based phone systems
come in many size ranges and it may be necessary periodically to scrap
existing systems and replace hardware; this is not the case with VoIP
Reduce operating costs. Because a VoIP exchange is based on software
rather than hardware, it is easier to alter and maintain.
Improve productivity. VoIP
treats voice as if it were any other kind of data, so users can attach
documents to voice messages or participate in virtual meetings using
shared data and videoconferencing.
Connect to customers. By adding a 'click to talk' button to its website,
a VoIP-enabled enterprise can put web users in touch with its customer
Dependable call management. Voice-related services, like follow-me roaming,
caller-ID, call forwarding and broadcast messaging, become simpler to
maintain and can be updated as needed by your employees.
Flexibility. A Virtual Private Network
(VPN) is an allocated amount of bandwidth on the public Internet where
public access is prevented through encryption. If your company has its
own VPN and combines it with VoIP, you can set up a fully functioning
office anywhere there is a broadband connection. Green-field sites can
be up and running in minutes not weeks
