The Most Reliable and Flexible Transcoding Cards on the Market

Sangoma’s D100, D150 and D500 voice transcoding cards are the most flexible transcoding cards on the market. They are offered in PCI and PCI express form factor and convert simultaneous channels of transcoding, support codecs such as G.729, G.726, G.723.1, G.722, and iLBC without affecting latency or host CPU resources. All models are field upgradable from 30 to 400 calls with our D100 and D150 models and up to 2000 calls with our D500. All codecs are fully indemnified; no additional licensing is required for their use. Our D150 is especially important for embedded and virtual machine environments where PCI cards are not an option.

Sangoma’s voice transcoding cards offer seamless transcoding for your Asterisk, FreeSWITCH or API environment.

Why Do You Need Transcoding Cards?

IP telephony applications commonly require the use of multiple voice codecs, used to digitally compress voice signals and save on bandwidth. Voice signals from the Public Switched Telephone Network (PSTN) come in the form of the G.711 codec, but the VoIP terminal equipment and networks can support a variety of different voice codecs, such as G.729, G.726, G.723.1, G.722, iLBC, etc. The VoIP infrastructure needs the capability to mediate between endpoints supporting different codecs, but this functionality requires digital signal processing tasks that are often costly and resource-intensive, and can affect the quality of the voice signals, if it introduces too much latency and delay.
