Description
D150-PMC-240 : Sangoma D150
Voice Transcoding PMC Card - 240 Sessions
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.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.
The D150 card allows to convert numerous simultaneous channels 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
running up to 30, 60, 120, 240 or 400 channels of any-to-any voice codec conversion, with unmatched quality. All codecs are fully indemnified; no additional licensing is required for their use.
