Transcoding Cards

Save on Bandwidth and Improve Voice Quality

Sangoma’s 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.
