Voice over Internet Protocol
What is it? VoIP is a way of sending voice over a data
network. Traditionally transmitting voice used up large
amounts of bandwidth so was very expensive. Converting voice
to data packets allows greater compression, and therefore
less bandwidth, reducing cost. IP networks were initially
and exclusively designed to carry data communications, but
technology has addressed the opportunity of converting voice
communications into data ‘packets’ and sending
them over the same, single, IP network. Hence the term Voice
over IP. In business applications a modern PBX will be able
to offer VOIP functionality via a ‘gateway’
device. Some PBX systems are designed solely for use in
IP applications; known as IP PBX, these systems deploy LAN
Telephony as well as utilising VoIP.
Why have it?
- If you can run voice and data communications over one
network instead of two then costs should be reduced.
- As stated above, IP is an enabler. Therefore using
VoIP would enable you to use new applications as well
as speeding up existing applications.
- Remote workers or offices are a fine example of where
VoIP can be both cost effective and highly functional.
Connected from their home or branch office via an IP
- Telephone, personnel can be logged in an out of call
centres, take and make calls with full PBX functionality
as if they were sitting in the main office.
Other Considerations
Do not confuse with LAN Telephony or Voice over the Internet
as these are different applications. LAN Telephony routes
all calls internally over an IP local area network as well
as externally over a raft of circuit options, which include
digital private circuits as well as switched public circuits.
Routing a call initiated on the LAN requires quality of
service (QOS) to be considered and often an upgrade to the
LAN is required to ensure acceptable voice communications.
CASE STUDY:
Check Communications were approached by a large corporate
to provide the best solution to their business telephony
needs; a requirement common to a company of its size and
complexity. A multi-site company with satellite branches
across not only the UK, but France and wider across mainland
Europe, call costs were mounting with each successful business
expansion. The challenge facing Check was to find a solution
that would provide seamless inter-communication across the
company’ offices, an exceptional telephone system
to ensure clients’ calls are dealt with professionally,
and critically, the best cost savings available using the
efficiencies in telecom technology today.
Having consulted extensively with Check Communications,
the client’s needs were explored and a bespoke VoIP
solution was offered. “Once successfully implemented,
the system exactly matches the client’s business needs;
both practically and on a fiscal level. The client’s
main UK based office now takes calls from satellite offices
across the UK and beyond, reaching as far and as wide as
their representatives care to travel; their inter-branch
calls are now made with no charge over the internet, via
their laptops. There are few greater Office efficiencies,
and Check is delighted to be at the forefront, and able
to provide the perfect solution.”
