Sangoma Transcoding Appliance NTG-AP1200 (1200 Sessions)

NTG-AP1200 Sangoma Transcoding Appliance - 1200 Sessions - NTG-LI1200; order 1x D500-300E separately

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, such as G.729, G.726, AMR, G.722, iLBC, etc. VoIP infrastructures need to include the capability to mediate between endpoints supporting different codecs, yet this functionality 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 NetBorder Transcoding Gateway 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.

The gateway allows running 400, 800, 1200, 1600, 2000 or 4000 channels of any-to-any voice codec conversion, with unmatched quality¹. All codecs are fully indemnified²; no additional licensing is required for their use.

The NetBorder Transcoding Gateway is a SIP back-to-back user agent, capable of handling SIP signalling traffic, that provides a stand-alone and flexible deployment option. The gateway is configurable via an user-friendly web management interface. The codecs offered during the codec negotiation phase of the call can be defined to meet specific environment requirements on a per call basis.

The NetBorder Transcoding Gateway is offered in the appliance format for an all-in-one turnkey solution. The option of an ISO software package to be installed on any server with a Sangoma D500 Transcoding board is also available.
