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.

Benefits of IP telephony :

The most significant benefit of IPT and driver of its evolution is money-saving and easy implementation of innovative services:

• In the future, Internet Telephony Service Providers (ITSP) may use a single infrastructure for providing both, Internet access and Internet telephony .

• Now, customers may take advantage of flat Internet rating vs. hierarchical PSTN rating and save money while letting their long-distance calls be routed over Internet.

• The IPT users may also profit of its software-oriented nature: software solutions may be easily extended and integrated with other services and applications.

What is Cisco system? One of the leading manufacturers of network equipment. Cisco's primary business is in internetworking products, such as routers, bridges, and switches.A large supplier of networking hardware and software, including router and security products.A company that makes network equipment. Cisco IP Telephony With voice now supported over our data networks, it is possible to remove the costly PBX and replace it with a voice and data gateway implementing IP Telephony. More likely than not the gateway could be a router which already exists in the corporate network .Corporate have traditionally separated their voice and data networks ,doubling the cost of equipment and maintenance, support staff and training .Today , voice and data can be consolidated into one , hence the costs are greatly reduced, if not halved. The voice world has many different applications to support call centre requirements, and now the world of voice and data is merging, it enables unified messaging of both media .The following outlines how Cisco switching, routing, and wireless solutions uniquely deliver these benefits with Cisco Unified Communications.

Deployment Benefits

• Faster, more cost-efficient IP phone moves, adds, and changes • Ensure optimum voice quality across the WAN • Secure IP Communications everywhere-from the endpoints to the network

infrastructure • Always-available voice

Operational Benefits

• Faster resolution of voice issue

4

• Reduced 911 costs and dispatching errors • Greater accuracy of voice configuration changes

Consolidation Benefits

• Consolidated Cisco Unified Contact Center voice recording • Scalable wireless voice services • Services integration, which simplifies the network • Video as a simple addition • Integrated services and support

Business Benefits:

• Reduce the cost of discrete voice and data networks into one network. • Reduce the cost of maintenance, support and training by supporting one

technology rather than two. • Increased return on investment. • Enables true unified messaging. • Increase the ease and functionality of a converged voice and data network.

Conclusion: Now-a-days IP telephony is most popular service of communication Such as 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 because of advantage of flat Internet rating vs. hierarchical PSTN rating and save money while letting their long-distance calls be routed over Internet. This is especially true in Europe, where the prices of long-distance calls are still higher than in US. Cisco IP telephony With voice now supported over our data networks, it is possible to remove the costly PBX and replace it with a voice and data gateway implementing IP Telephony .Cisco is a well known networking company they give the IP telephony solution is most popular because of easier deploy new communication services ,Strong security and availability ,Higher operational efficiency, greater consolidation and scalability, open standard and innovation and lowest call cost of ownership .This assignment is just overview of Cisco IP telephony solution and installation & configuration. Cisco looked to IP Telephony to increase personal and workgroup productivity, improve its ability to respond to customers, and reduce operational costs.
