The market for VoIP services in Asia is growing rapidly, with total revenue projected to jump from US$5.5 billion in 2004 to over $10 billion by 2009. The market is largely driven by long distance calls, initiated from traditional PSTN terminals or from full IP local loops, and carried over IP backbones to the destination's local network. Long distance calls accounted for 85.4% of total revenue in 2004. However, with the advent of VoIP, this percentage is starting to erode.
The rapid growth of Asia voip has been met with some challenges, however. The development of competition is hindered by tight regulatory environments that attempt to protect state-owned telecommunications companies. In-Stat, part of IDG Communications, predicts that the number of VOIP users in Asia will reach over 20 million by 2009.
VoIP deployment in Asia is at an early stage, but is expected to grow strongly in the next five years, especially in countries with legacy infrastructure. Reasons for this growth include cost savings in network equipment, competitive international wholesale rates, and a migration path to a fully converged network. While the quality of VoIP calls is often regarded as sub-par, it has recently improved to the point where it is competitive with switched calls. This trend is likely to continue.
Some of the top VOIP providers in Asia include AoneVoice, Sunrise Telephone Systems, and VoIP. Sunrise offers a range of VoIP services for small and medium-sized businesses. They have offices in Tokyo and Australia, and can deploy multi-site VoIP solutions throughout the Asia Pacific region. For clients in other parts of the world, they can opt for local partners for support. These providers are often multi-site, and most have proven success.
As VoIP has become a mainstream technology, companies in Asia have expanded their manufacturing capabilities. The FCC has mandated that VoIP providers provide emergency services. VoIP providers can identify callers based on IP addresses. It is possible to track callers using the IP address, and even trace their location. VoIP services use different codecs and protocols, including the G.729.1 protocol and the SILK codec, which is prominently used in Skype.
To help determine market size and growth potential, the research team at Global VoIP Research has examined the region's VoIP market by application and type of product. These three segments are further studied in terms of market size, CAGR, revenue, and consumption. Compared to landline phone calls, VoIP does not provide the same call quality. Therefore, VoIP calls may not be suitable for making vital business calls. And VoIP services may not be available in every country.
While VoIP calls may sound crisper than those made with landlines, the clarity of the sound depends on your internet service provider. SIP protocol allows you to use error-correction protocols (TCP and UDP). Additionally, cloud PBX providers can forward calls to a cell phone. If your home is a power outage, you won't have to worry about missing your call - your VoIP phone will automatically forward the call to the cell phone. During a power outage, 911 operators may not know where to send help because VoIP phones aren't mobile-ready.
