  3. The Need of the innovation • Teleconferencing is an essential feature in any business • telephone system. A teleconference allows associates to • engage in a group discussion by conducting a virtual • meeting while remaining at geographically disperse • locations.

  4. bandwidth-efficient • In a VoIP telephone system, research and inquiry about challenges of providing a teleconference feature that can support a large-scale teleconference without using excessive bandwidth.

  5. Basic and Applied Research An audio teleconference feature with current technology sums or mixes the audio inputs from all of the conference participants to produce a mixed audio stream that contains the audio from everyone in the conference.

  6. Problem -Situation In a teleconference server application, the server supports a large number of participants in a single conference. This introduces an additional challenge. The teleconference server can no longer sum the audio of all the participants. Summing the audio of a large number causes overflow in the audio, thus distorting the audio and degrading the audio quality.

  7. Development • The new system allows a network with a • given capacity to accommodate almost double the number of conference participants that an existing system would allow. The new approach • consumes considerably less data bandwidth than existing systems require. The audience at a teleconference allows associates to • engage in a group discussion.

  8. Commercialization This new teleconference technique reduces the number of server transmissions from multiple unicast transmissions down to a single multicast transmission. The advantage of this new technique in terms of reduced bandwidth • consumption increases tremendously when the number of participants in a conference grows. For a 100-participant conference, this new approach requires 100 incoming audio streams and only one outgoing mixed audio stream.

  9. Consequences • Analysis of Bandwidth Savings • To quantify the bandwidth improvement that our system achieves, consider implementations with various codes. The computed results for server implementations with the ITU-T (International Telecommunication Union Standardization Sector) standard G.729A codec [7], the Internet Low Bitrates Codec (iLBC) [5], and the G.711 Pulse Code Modulation (PCM) codec [6].

  12. S-Curve Teleconference using a video link. Simply due to costs, teleconferences are frequently limited to audio links (telephone or computer-based).

  13. INNOVATOR Guinness World Records, ACT holds the record for the largest telephone conference call, which connected 10,424 people.

  14. Relative Advantage • Conferencing services range from on-demand, self-service to customized global multimedia events. Local dialing is available for participants in more than 65 countries. ACT is ISO 9001:2000 certified in the U.S. and is pursuing Six Sigma certification

  15. Compatibility • Demand is driven by the construction needs of companies and governments and the desire of industrial customers to improve the efficiency of operations. Profitability depends on the ability to accurately predict costs for a project. Small firms, which can effectively compete with larger ones by having expertise in a particular field, are often hired as consultants on larger projects if they have special expertise. Large firms are advantaged in designing and managing large projects.

  16. Complexity • Services Audio Conferencing, Web Conferencing, Video Conferencing, Video Event Services

  17. Trial Ability • VoIP: Getting down to basics The significance of "IP" in VoIP : Besides being an acronym for Internet Protocol, it means that voice services are no longer tied to a specific network. VoIP also provides enterprise organizations with a significantly more network design flexibility.

  18. Observability • A pure IP PBX is a software-based version of a traditional PBX that delivered in an appliance. The pure IP PBX replaces the traditional TDM PBX. The data network is then used to deliver voice services. A pure IP PBX offers a high degree of flexibility in where the call control is located. Normally, migrating from TDM to IP is not a one-to-one replacement. Companies often rationalize the number of IP PBXs.
