2. What is IP Telephony?
IP telephony (Internet protocol telephony) is a general term for the
technologies that use the Internet Protocol's packet-switched connections to
exchange voice, fax, and other forms of information that have traditionally
been carried over the dedicated circuit-switched connections of the public
switched telephone network (PSTN). Using the Internet, calls travel as
packets of data on shared lines, avoiding the tolls of the PSTN. The
challenge in IP telephony is to deliver the voice, fax, or video packets in a
dependable flow to the user. Much of IP telephony focuses on that
challenge.
IP telephony service providers include or soon will include local telephone
companies, long distance providers such as AT&T, cable TV companies,
Internet service providers (ISPs), and fixed service wireless operators. IP
telephony services also affect vendors of traditional handheld devices.
Currently, unlike traditional phone service, IP telephony service is relatively
unregulated by government. In the United States, the Federal
Communications Commission (FCC) regulates phone-to-phone connections,
but says they do not plan to regulate connections between a phone user and
an IP telephony service provider.
VoIP is an organized effort to standardize IP telephony. IP telephony is an
important part of the convergence of computers, telephones, and television
into a single integrated information environment. Also see another general
term, computer-telephony integration (CTI), which describes technologies
for using computers to manage telephone calls.

Difference Between IP Telephony and VoIP
IP telephony enables voice communication over internet protocol (VoIP)
networks. It unites an organization's many locations - including mobile
workers - into a single converged network. It promises cost savings by
combining voice and data on one network that can be centrally maintained,
as well as by eliminating toll expenses for calls between locations.
IP telephony works by converting voice communications into data packets.
Telephones are connected to data ports on the IP network. But the function
of a telephone can easily be provided using a device that is already
connected to the network - the PC.
Terms such as client-server telephony, telephony-enabled LAN, pure IP
telephony, converged telephony, and LAN telephony all describe the same
fundamental, distributed IP telephony architecture. Simply put, companies’

4. supports both distributed (client-server) IP telephony and IP-enabled PBXs
without forcing customers-to-compromise-on-either-approach.
Instead of a separate, multi-line phone beside the PC at each desk, IP
telephony allows software on the PC to serve as a "soft" phone. Software,
unlike telephone hardware, is easily upgraded and enhanced, without work
disruption, without equipment-cost-without-even-visiting-every-desk.
The concept of transmitting voice over a data network is exciting to
companies that are maintaining intranet connections for all of their branch
offices, while paying for voice circuits to PBXs in those same locations. The
cost savings alone are appealing - although security, reliability, and quality
questions can make network managers apprehensive about IP telephony.
That's why companies’ offers comprehensive solutions for delivering
secure,-scalable-IP-telephony-across-the-enterprise.
Avaya combines these solutions with services to ensure that the network will
handle voice with the utmost quality and reliability. companies’ Services
help companies select the right solutions, assess the readiness of the LAN to
carry voice traffic, implement the solutions, and maintain them after
installation.
IP Telephony converged network secure
Converged networks require converged security that expands traditional data
security policies and procedures to protect the privacy of all network
information, including IP Telephony traffic, since IP telephony can
introduce unauthorized entry points into the network. Also, traditional data
security practices can impact IP Telephony voice quality if not engineered
correctly. So, a converged network must be designed to comply with IT
security policies for voice and data, while not impeding the performance of
critical network applications.
Converged security services start with a Security Assessment, to identify the
network “gaps” that can be exploited by an attacker. Security Policy
Development defines the procedures, responsibilities, controls and security
measures required to protect assets in a converged environment. That
preparation supports the Security Architecture & Design, which brings
expertise to the complex task of designing a secure information
infrastructure within converged networks. Architecture & Design ensures

5. that the security measures defined in a policy are designed into the security
framework.
Its also helps satisfy corporate security policy requirements by allowing
network access control and providing secure, proactive application
maintenance & monitoring in a converged environment. This secure remote
maintenance solution also provides the reporting necessary to demonstrate
compliance with security, data integrity and privacy regulations. Managed
Security Services builds on these capabilities by providing security through
the extended perimeter of an enterprise’s voice, data and IP networks.
Managed Security Services offers additional regulatory compliance support
through proactive and real-time event reporting, audit trails, forensic
analysis, and intrusion detection and incident responses that strengthen
security for the networks monitored.
Ten Reason to Implement IP Telephony
1. Cost Savings: reduce inter-sites and long distance charges especially
international calls
2. Simplified Operations: consolidation of all key resources in data centers,
real plug& play deployments on remote sites and integrated management
enable our customers to fully benefit from centralized operations
3. Embedded Call Center capability: industry-leading call center is built in
IP Telephony solution just waiting to be activated
4. Users directly benefit from IP Telephony: Soft phone command center
enables control of telephone from user’s desktop. All users receive HQ-
functionalities even in remote branches. Improved user efficiency converts
directly in increased productivity
5. Productivity of mobile employees: Extension to Cellular delivers
powerful functionalities to mobile users: one-number for all user’s phones &
fax, seamless toggle between desk and mobile phones, access to top 20
telephony features from GSM phone and single mail box are some of the
features

6. 6. Tolerate poor network quality: Soft phone works around lack of
bandwidth or poor network quality and delivers a practical solution to distant
workers
7. Smooth Migration: Customers choose their pace of evolution toward IP
communication.
8. Minimize operational cost: IP Telephony has been carefully designed to
avoid hidden cost. For example servers are delivered as appliances so
hardware and operating system are also covered by maintenance; updates
may be applied hot and remotely; closed controlled systems eliminates need
for anti-virus and its update
9. Reliable for business continuity: Rock solid system availability with
multiple resiliency levels reinforced by its EXPERT SystemsSM Diagnostic
Tools for remote monitoring & maintenance
10. Security: end-to-end protection of each IP call; innovative “secure by
design” architecture; hardened servers and infrastructure; secured
management; all assist in strong IP Telephony security.
Vote
1. a) A formal expression of preference for a candidate for office or for a
proposed resolution of an issue.
b) A means by which such a preference is made known, such as a raised
hand or a marked ballot.
2. The number of votes cast in an election or to resolve an issue: a heavy
vote in favor of the bill.
3. A group of voters alike in some way: the Black vote; the rural vote.
4. The act or process of voting: took a vote on the issue.
5. The result of an election or referendum.
6. The right to participate as a voter; suffrage.

7. Implementation Voting System Through IP Telephony
To setup IP Telephony we need conventional Phone, soft phone (Personal
Phone), IP Telephone, GSM gateway server, Asterisk server, VoIP gateway,
VoIP enable Wi-Fi phone. Using these things we setup a IP Telephony
server. For voting system/service we need a voting server with a database
service. For using voting system we need IP enable voting pad or we can use
IP enable telephone’s keypad for voting. After given vote, voting server and
its database preserve voting information and synchronous different candidate
voting information and count individual candidate’s number of vote and
Ranks candidate position according to number of vote.
Voting System through IP telephony implementation challenges
• Numerous standards exist in support of voice and data networks. How
will these standards be applied to a converged network.
• Voice network are ultra reliable. How will this reliability be translated
into the converged network.
• Interoperable in different vendors equipment
Business and Profitability
Voting system Through IP telephony is a very profitable system. Because It
Helps people’s to reduce their communication & time and other cost. So
people accept this system very easily. In on other hand those who provide
Value added service (VAS) through IP Telephony for voting purpose , they
get lot of customer because it helps people lot. If service provider take few
marginal profit they get lot o money or profit.
