Just a few year age, Voice Over IP (VoIP) was considered a novelty, but with annual growth rates of more than 20 percent, adoption of this service is widespread throughout the business and private sectors. Some analysts estimate that almost 40 million people will be using some type of VoIP service by 2010. For enterprise customers, which already rely on IP communications for e-mail, messaging, and, now, videoconferencing, the shift to VoIP is a natural evolution.

However, there are some who question why it has taken so long to get to this point. One hurdle to widespread adoption was the lack of interoperability among manufacturers, which made it difficult for companies to communicate with others not using their own telephone system.

To overcome this, service providers are adopting Session Initiation Protocol (SIP) as a standard for VoIP communications, and manufacturers of VoIP products are increasingly adhering to International Telecommunication Union (ITU) standards — both narrowband codecs, such as ITU G.711, wideband codecs, such as ITU G.722, and standard codecs for voice compression, such as ITU G.722.1. “Users want choice, they don't want to be locked in, and they want network devices that are fully interoperable,” says Chalan Aras, vice president of marketing of the voice communications division at Polycom.
