XConnect's HD Voice Peering Trial: Focusing on Who Rather Than How

XConnect's recently announced plan for a trial HD voice peering federation marks a significant advance in the move to HD communication. The trial, to take place between April and June of this year, will directly connect providers offering HD voice services. That will let them pass HD calls, which provide audio quality superior to that of conventional PSTN phone calls, to one another rather than just among their own customers. The trial thus represents an effort to start building a critical mass of HD-capable voice subscribers. As such, it is as much a commercial effort as a technical one.

The Top 25 VoIP Advances of 2009

There were more advances than true innovations in the VoIP world in 2009. That's because some of the most important developments had more to do with commercial and political maneuvers than with technical creativity. Still, such maneuvers often helped spread the benefits of VoIP as much as did technical innovation. And collectively, the advances brought some already-evident trends into clearer focus. A key such trend is the increasing integration of voice with other applications and services. Another is the intensifying interest in HD voice. A third is the growing interconnection of VoIP services, in part in response to the possibilities that end-to-end HD voice offers. With such trends as background, here, in no particular order, are our top 25 VoIP advances of 2009.

Nimbuzz First Customer for GIPS Android HD Codec

The most widely recognized obstacle to mobile VoIP running over cellular data networks is carriers' opposition. Mobile operators don't want to allow services that compete with their lucrative voice minutes businesses to run over their networks, because it means all they'll get paid for is transporting the bits carrying the voice, a far less lucrative business. A less-known obstacle to the service is call quality concerns. Regular voice calls can sound bad enough, but delivering them over a data network not designed with real-time services like voice in mind. A Global IP Solutions (GIPS) answer to the latter problem is now available for Android users.

Japanese Web Conferencing Provider ANET Employs GIPS Video ConferenceEngine

Cutting travel expenses by video conferencing is becoming a universal practice. It's particularly useful when the travel being avoided is, say, trans-Pacific. But developing the underlying technology necessary to make it work can be challenging. Video processing software has to deal with a lot of challenges. The most vexing of these may be the different bandwidth levels connecting conference participants. A newly announced deal in Japan by Global IP Solutions (GIPS) shows that the solutions can be universal as well.

GIPS Codec Now Powers Yahoo Video Calling

When it comes to real-time Internet communication, quality is always an issue. Internet connections are so inconsistent they can turn talk into gibberish. It takes sophisticated technology to make Internet conversations sound consistently good. The challenges are even greater with Internet video calling. The quality of both images and sound has to be good, and the two must also be in sync. That's why companies that can afford it pay lots of money for custom video equipment connected over private IP links.

Codecs are key to making Internet voice and video work. These pieces of software, embedded in physical phones or Internet calling applications, process the audio and video for delivery over IP connections. Among other things, codecs adjust for different levels of Internet bandwidth between callers, and compensate for delay, inconsistent delivery and loss of packets carrying the voice or video streams.
