Evolution of convergence and VOIP

1. Evolution of Convergence and VOIP Presented By: NanditaTiwari Vijay Deep Shukla UtkarshVerma

2. Convergence Convergence can refer to previously separate technologies such as voice (and telephony features), data (and productivity applications) and video that now share resources and interact with each other, synergistically creating new efficiencies. Technological convergence is the tendency for different technological systems to evolve towards performing similar tasks. An often used example is when separate technologies such as voice, data and video come together to share resources and interact with each other.

4. E-mail and World Wide Web access via digital TV decoders and mobile phones;

5. Web casting of radio and TV programming on the Internet;

6. Using the Internet for voice telephony Convergence eliminates the need for duplicate hardware and special vendors.

7. Why Convergence? VoIP/IPT Industry Trends Enterprise Experiences and Best Practices

8. Voice over IP: Carrying voice over IP Used to refer to trunking across the WAN Now a “catch-all” term for anything related to voice & data convergence IP Telephony: Using IP phones Refers to extending IP all the way out to the desktop Examples: IP Trunking between PBXs with digital handsets = VoIP IP phones throughout the organization = IP Telephony

9. Overview Voice over IP/IP Telephony Represents the PRESENT of Enterprise Communications Both internal and external Brings convergence to multiple forms of communication Saves money and improves productivity But…… VoIP is unlike most (if not all) applications on the network Performance must be guaranteed Availability must be guaranteed A successful deployment of VoIP means addressing infrastructure and management issues BEFOREimplementation 6

10. Why VoIP? TDM voice is stable, cheap, has worked for years, and delivers the services needed So why Replace It ?!?!?!?!?! invest in training and Operations Administration and Maintenance an infrastructure upgrade IP Telephony is immature and insecure might not save money So why are we doing this? 7 ?

11. IP Telephony’s Promise Because We may actually lower costs after all Simplified network infrastructure Reduced MAC costs Rapid Feature/Application deployment IP Telephony utilizes the Internet architecture, similar to the World Wide Web Applications and Services can be distributed throughout the network Adoption of the Internet Model – distributed applications sharing a common infrastructure Security capabilities offer better protection than older voice systems 8

12. IP Telephony’s Promise Standard Protocols TCP/IP and related protocols (H.323, MGCP, SIP) Allows for multi-vendor interoperability Provides more product choice (someday) Ubiquitous Access Plug your phone in anywhere you have an Internet connection Soft phones on your PC/Laptop/PDA Service Creation No longer requires call control be on premises New opportunities to outsource 9

13. Industry Trends VoIP/IPT Industry Trends: Voice is converging with collaboration SIP is emerging as the de-facto standard for system interconnection, followed by H.232 More services are emerging Open source is becoming viable Security concerns are getting a lot of attention 10

14. The Big Picture Goal: a single communications infrastructure unifying collaboration, real-time communications, and presence Convergence not of voice & data, but rather convergence of all forms of real-time communications into a unified interoperable environment Combined with collaboration tools Integrated into business applications & processes Extensible beyond organizational boundaries Delivering measurable business benefit by streamlining and improving the ability for individuals and groups to communicate Voice but just one component of a converged communications & collaboration infrastructure: voice, video, instant messaging, conferencing, collaboration and presence as a unified application 11

15. Enterprise Experiences Enterprises are gradually implementing IP telephony Network management remains the paramount challenge 12

17. End of lifecycle replacement of legacy systems

18. Modernization/transformation of call center operations

19. Growth of enterprise VoIP is accelerating

20. ~ < 12% of PBX market is replaced annually

21. VoIP equipment revenues have surpassed legacy revenues in 2006

22. Convergence is a positive impact on enterprise

23. Security and survivability are concerns but can be managed/overcome13
