is IP Telephony?
or VOIP (Voice Over Internet Protocol) is the transmission
of telephone calls over a data network. This is accomplished
by packetization of the voice streams. VOIP enables users
to make telephone calls over a data network like the Internet.
VOIP converts the voice signal from the telephone into a digital
signal that can be transmitted across the data network. At
the receiving end the signal gets converted back to voice.
The basic telephone functions between traditional voice and
VOIP are identical. Users pick aup the receiver, hear dial
tone and dial numbers as they’ve done in the past. In
fact, many VOIP users are unaware that they are not on a traditional
PBX phone system until they learn about the additional features
and functions that an IP Telephony system provides.
are the benefits of IP Telephony?
may use a single infrastructure for providing both Internet
access (data) and Internet telephony (voice). Only data-oriented
switches need be deployed for moving data as well as packetized
from two separate networks to one powerful converged network,
an IP Telephony solution provides immediate cost reductions
in both staffing and maintenance of hardware and software.
of voice and data may facilitate the implementation of such
cutting edge applications as unified messaging, multimedia
conferencing, collaborative contact centers, and interactive
multimedia response systems. These applications help organizations
realize business gains by improving operational efficiencies,
increasing productivity, and enhancing both user and customer
Solutions allow telecommuting employees to become more productive
by granting access to all the capabilities of the telephony
can IP Telephony save money?
IP Telephony eliminates the cost and administrative overhead
required for separate voice and data networks. Why buy, support
and manage two separate networks when all you need is one?
Calls between branch offices may take advantage of existing
IP network connectivity as opposed to paying for PSTN (Public
Switched Telephone Network) calls thereby saving money by
routing long-distance calls over the IP network.
office PBX: The remote branch may be set up to appear as an
extension to the main branch, enjoying the same voice-mail,
conferencing, and desktop handsets as the central branch,
but without deploying a local PBX to handle off-network calls.
Start-up Costs: Deployment of new IP telephony services requires
significantly lower investment in terms of time and money
than in the traditional PBX environment.
ROI: Investment payback in most cases is usually achieved
within 12-18 months following installation.
are the components of an IP Telephony system?
systems are composed of these basic elements:
devices: these may be IP phones, traditional telephones
and/or audio-equipped personal computers.
handle signal translations between traditional telephone
equipment and IP network devices.
the gatekeepers/proxies provide centralized call management
functions such as user location, authentication, bandwidth
management, address translation, etc.
There are so many vendors out there. How do I choose an IP
Telephony solution should be reliable, scalable, standards-based,
and provide the features and functionality that would meet
your business needs.
systems employ distributed architecture that eliminates dependency
on any single component for redundancy and reliability. And
adding users or a new branch office is easier and relatively
inexpensive compared to a PBX-based system.

and at a rate that suits your business requirements.
Initiation Protocol (SIP) is a signaling protocol used for
establishing sessions in an IP network. A session could be
a simple two-way telephone call or it could be a multi-user/multi-media
conference session. The ability to establish these sessions
means that a host of modern services become possible.
emerging as the protocol of choice for setting up conferencing,
telephony, multimedia and other types of communication sessions
on the Internet. SIP may also be used for new types of communications,
such as application-level mobility across various networks,
including wireless, and across user devices.
How does SIP work?
a request-response protocol that closely resembles two other
Internet protocols, HTTP and SMTP (the protocols that run
the world wide web and email). SIP transforms telephony into
just another web application and thereby facilitates easy
integration with other Internet services.
than defining a new type of addressing system, SIP addresses
are much the same as an email address.
the following basic communication functions:
are the advantages of SIP?
establish multi-user sessions regardless of media content.
SIP achieves this by the opening, modifying and closing of
sessions over IP networks. These sessions could be as basic
as a telephone call or as complex as a multi-party mixed media
use of open Application Programming Interfaces (APIs) where
customized services may be programmed and deployed that combine
elements from telephony and other web applications such as
email, messaging, video streaming and the Internet.

are the components of SIP?
are two basic components within SIP: the SIP user agent and
the SIP network server. The user agent is the end system device
such as a cell phone, PDA, multi-media handset, or PC. The
SIP server is the network device that handles call signaling.
The main function of the SIP servers is to provide name resolution
and user location, since the caller usually does not know
the host name or IP address of the called party.
don’t want to be a “Beta” site for an unproven
technology. Is SIP a standard?
the last couple of years, SIP has been adopted as the protocol
of choice for signaling. SIP is an RFC standard (RFC 3261)
from the Internet Engineering Task Force (IETF), the body
responsible for administering and developing the mechanisms
that power the Internet.
number of carriers and ISPs are offering SIP-based services
such as local and long distance telephony, presence and Instant
messaging, push to talk, rich media conferencing, and more.
variety of SIP-enabled voice systems and phones are available
that give consumers flexibility of choice and cost.
can I tell if a SIP-enabled phone system is right for my business?
a phone system for your business is a decision that cannot
be make lightly. A modern phone system must meet the following
basic requirements. It must:
the specific requirements of your business
to meet future needs as your business grows
maximum use of 21st century features and functions
