Consistent Voice Quality For VoIP Conferencing

HIGHLIGHTS

  • Measure the subscriber's exact call experience
  • Intelligently deploy codec transcoding to maximize flexibility
  • Mitigate call impairments such as noise and echo in real time

The cost benefits of VoIP have found a home in the conferencing market.

The conferencing market consists of communications providers who offer teleconferencing services to corporate clients. These clients rely on conference calls to conduct business, and use mobile phones as frequently as speakerphones. There is little tolerance for poor voice quality.

Attractive pricing and high-value voice quality now are requirements in this market, and drive the decisions carriers make about network technologies.

We offer a solution that solves the most critical problems in delivering reliable voice quality over IP conference bridges: interconnectivity, capacity and voice impairments.

Equally important, optimizing voice requires a full understanding of what users on the bridge are experiencing, and quantifying the impact on voice quality of all the variables in the network and in each user's environment. We deliver this knowledge to our customers, and coupled with mitigating these impairments in real time, the opportunity we provide to the conferencing industry is compelling.

The need to compress speech to better utilize network capacity has caused an explosion in the variety of codecs used to encode and decode voice into packets for transmission across IP networks. To ensure interconnectivity for their customers and partners, and to make the most efficient use of network capacity, conference providers now must support a variety of codecs without decreasing network performance or degrading voice quality.

Additionally, VoIP networks introduce a new set of voice quality challenges, such as mismatched speech levels and longer transport delays, which cause a dramatic increase in the amount of echo experienced. For customers using low bitrate codecs, such as those accessing the bridge via home DSL or cable modem connections, background noise can have an additional detrimental effect on voice quality.

Ditech's Codec Transcoding product, combined with our Voice Quality Assurance product, solves these problems and give service providers the ability to intelligently optimize the end-to-end call experience.

  • Service providers now can measure the end-to-end quality of the call experience to help manage customer service and SLAs.
  • Network planners can deploy codec transcoding to maximize flexibility and cost while minimizing the impact on voice quality.
  • Operations can mitigate impairments such as noise and echo in real time, reducing customer complaints and driving service usage.

The result is reliable, consistent voice quality on conference bridges and an R-Value (and the resulting Mean Opinion Score) that attracts clients.
