Transcoding is a reality in VoIP Networks. Whether your telecom application requires compression codecs  to save bandwidth or to improve voice quality Xaccel has the most flexible transcoding service today!

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 Xaccel Codec Transcoding Service acts like a B2BUA that converts simultaneous sessions of transcoding from one type of codec (e.g. G.711) to another (e.g. G.729).

Unlike other providers we dont do unreliable CPU intensive software based transcoding.

Our service uses a state of the art system based off hardware Digital Signal Processor’s (DSP’s) that transcodes with no increase in latency and provides the best call quality.

Have a poor Internet connection ? Looking to improve your voice quality or to run more calls over your current connection then our service is for you. We work with any SIP trunking provider and can do transcoding on both in and outbound calls.
