The latest offering from our transcoding cards family adds more deployment options for the embedded markets, where host-based processing is restricted and the small form-factor of appliances limits the addition of PCI cards.

• 30 to 400 transcoding sessions
• Works on Asterisk® and FreeSWITCH®
• Compact 2U Form-Factor, Stand-Alone Boxed
  Enclosure or PCI Mezzanine Card Option
• RJ45 Ethernet Interface

• Most IP telephony applications require the use of multiple types of voice codecs, which are used to digitally compress voice signals, to save on bandwidth requirements. While voice signals from the Public Switched Telephone Network (PSTN) always come in the form of the G.711 codec, the VoIP terminal equipment and networks support a variety of different voice codecs including such as G.729, G.726, AMR, G.722, iLBC, etc. VoIP infrastructure most often needs to include the capability to mediate between endpoints supporting different codecs, yet this functionality often requires digital signal processing tasks that are often costly, 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.

  • Hosted iPBX / IP Centrex
  • Distributed PBX
  • IP Network Peering
  • SIP Trunking
  • VoIP Gateways
