Sangoma NBTG-AP4000 NetBorder Transcoding Gateway Appliance – 4000 Sessions Overview

The Sangoma NBTG-AP4000 is an all-in-one turnkey 1U transcoding gateway appliance which allows the running of 4000 channels of any-to-any voice code conversion. The NBTG-AP4000 can be used for bandwidth savings for SIP trunking deployments, remote call center agent pools, carrier IP network peering and HD Voice over IP deployments.

Sangoma NBTG-AP4000 NetBorder Transcoding Gateway Appliance – 4000 Sessions Overview

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 Sangoma NBTG-AP4000 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 NBTG-AP4000 allows running of 4000 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 Sangoma NBTG-AP4000 NetBorder Transcoding Gateway Appliance is a SIP back-to-back user agent, capable of handling SIP signalling traffic, that provides a stand-alone and flexible deployment option. The NBTG-AP4000 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.
