Sangoma D100-030 Product Overview
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 D100 card, available in PCI and
PCI Express form factors, converts
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 up to 30,
60, 120, 240 or 480 channels of any to-
any voice codec conversion, with unmatched quality¹. All codecs
are fully indemnified; no additional licensing is required for their use.
The D100 works with both Asterisk® and FreeSWITCH™.
drivers, these applications can use the D100 cards as seamless voice
