The Sangoma D100-240E delivers a maximum of 240 simultaneous transcoding sessions, which supports IP telephony environments with equipment requiring use of different codecs. Most IP telephony applications will require the use of multiple voice codecs, used to digitally compress voice signals and use less bandwidth. Oftentimes, transcoding requires digital signal processing tasks that are costly and resource-intensive, which can negatively affects the quality of voice signals.
Voice signals from the Public Switched Telephone Network (PSTN) are available in the G.711 codec, but common VoIP terminal equipment and networks will support a variety of different voice codecs, such as G.729, G.726, AMR, G.723.1, G.722, iLBC.
The D100-240E is a PCIe voice transcoding card that converts up to 240 simultaneous channels of transcoding from one type of codec (for example, G.711) to another (such as G.729), without introducing latency or using host CPU resources. The card enables up to 240 channels of any-to-any voice codec conversion, which will deliver unmatched quality*. All codecs are fully indemnified and no additional licensing is required for their use**.
