Transcoding/Media Adaptation

The inherent flexibility of IP enables multiple communications methods for transmitting VoIP and multimedia sessions in service provider networks, creating significant interoperability challenges at network borders. GENBAND, a pioneer in session border control and IP media adaptation, provides scalable, carrier class solutions to ensure high quality, highly interoperable communications between IP network borders.

Fixed and mobile access networks are often bandwidth-constrained, resulting in many different, incompatible codecs that encode and decode the voice content for more efficient routing over the IP network. Traditional methods of resolving this IP-to-IP border incompatibility have included using media gateways as the intermediary to transcode each respective IP session to circuit-switched G.711, but this as well as end user devices -- or even the IP network itself -- can result in voice quality impairments such as delay, jitter, echo, and packet loss.

GENBAND's S3 Session Border Controller, S2 and S9 Integrated Border Gateways (IBG), and G9 Converged Gateway provide comprehensive transcoding and media adaptation for service providers. Using the S-Series gateways as media resource controllers, the G9 -- with its powerful, state-of-the-art DSP resources -- serves as an efficient media resource processor for transcoding mobile codecs like mobile AMR and EVRC as well as fixed line G.711, G.729, and a wide variety of other codecs. This solution also provides media adaptation like echo cancellation to resolve other voice quality impairments.
