  • A Short Note on Voting System through IP Telephony Prepared for: Dr. Mashiur Rahman Instructor, ETE Program, Dept. of Computer Science & Engineering, North South University Prepared by: Rubaiyet Rashid Romel ID: 063-454-056 Course: ETE-605/ IP TELEPHONY Submitted on 15th April, 2008 Spring Semester 2008 North South University
  • 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.
  • Fig: IP Telephony Lab 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’
  • 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
  • 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. 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.
  • 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.
