VoIP- High Definition (VoIP - HD)
In the past 10 years, Voice over IP has emerged as an alternative to the traditional Telephony (PSTN) allowing a reduction in costs and increased capacity on long-distance telephone calls.
While providing for lower costs and greater flexibility on converged voice and data networks, VoIP in general failed to deliver ‘better-than-PSTN’ quality, mainly due to the 3.4 Khz bandwidth limitation of legacy narrowband speech codecs.
Consider when ISDN came to Australia, it initially was considered a low quality service, today however it is considered the most stable of Line and Data Services.
VoIP today when correctly designed to capitalize on expanding IP broadband networks and wideband speech codecs can now be effectively deployed. Xcomm recommends any VoIP service have a backup component to complement the service.
Xcomm VoIP-HD solutions offer a broad range of feature-rich and scalable products supporting VoIP-HD quality utilising the most popular wideband coders such as G.722, G.722.2, G.729.1, G.711.1 and Microsoft RTA.
Enhanced Algorithms and Services that enrich the VoIP-HD experience included in our VoIP-HD equipment offering's are:
- Packet Loss Concealment
- Acoustic Echo Cancellation
- Adaptive Jitter Buffers
- Wideband Voice Conferencing
- Wideband Media Transcoding
VoIP-HD enables the doubling of bandwidth for voice communications, allowing the elevation of daily voice communication to be similar to digital FM radio or conference room quality.
