Availability: In Stock
Sangoma D500-500e PCI Express Transcoding card with 5 transcoding modules (Up to 2,000 Transcoding Sessions)
The industry’s highest density transcoding card - designed for optimum voice quality for high port count systems, offering from 400 to 2,000 transcoding sessions in one compact PCIe form factor!
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, AMR, 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.
The D500 card converts numerous simultaneous sessions of transcoding from one type of codec (e.g. G.711) to another (e.g. G.729), without affecting latency or using up precious host CPU resources. The card allows up to 2,000 sessions of any-to-any voice codec conversion, with unmatched quality¹. All codecs are fully indemnified no additional licensing is required for their use².
The D500 works with both Asterisk® and FreeSWITCH®. With compatible drivers, these applications can use the D500 cards as seamless voice transcoding resources. Alternatiely, developers and integrators can use the Transcoding API in C for their own application development.
