The fact that the Internet opened up a whole new world of communication options has not been lost on those providing telephone service - or on those who spend lots of money on voice communication. The ever-changing technology and emerging market for more cost-effective and better communication is creating a demand for people who can create, design and install VoIP systems. There's also a growing market for those who can repair and maintain those systems.

So what's so great about VoIP and Internet telephone systems? Cost is probably one of the biggest benefits touted by the companies providing the services and one of the biggest reasons so many people are ready to try the market. With VoIP and Internet telephone options, there's no cost for long-distance calls - even to foreign countries which is typically very expensive for those companies that make those kinds of calls. Think it's impossible that someone would offer unlimited long-distance for nothing? You actually already have that option already in the form of email and chat. All you need is a microphone for instant voice communication in a chat room, and that form of communication is free with your paid Internet connection.

VoIP and Internet telephone systems just take that to the next level through a voice communication system that allows faster and clearer streaming than through a traditional Internet computer connection.

So if it's so great, why isn't everyone using VoIP and Internet telephone service? There are some drawbacks. The first and most important is availability. Though this is improving, you may not be able to connect to your VoIP or Internet telephone connection from just anywhere you happen to be. For busy company officials and even individuals, this is a serious lack that makes the system less attractive.

Another drawback comes in the form of emergency calls. According to some sources, the VoIP systems are seriously inadequate in emergency situations. Because of limited availability of services, it's very possible that users may not have the ability to make calls at all. Even if calls are possible, the systems are sometimes not sending signals to the nearest towers, meaning you may not be contacting the most local emergency response teams. It's also sometimes difficult for those emergency personnel to target your location. All these problems will likely be dealt with over time, but they're still concerns to some people now who rely on cell phones for emergencies and are reluctant to take the chance that their VoIP or Internet telephones will work in emergency situations.

The legalities almost always become an issue and VoIP is no exception. Because this type of communication has the potential to have a major impact on the communication industry, there's little doubt that it'll eventually be regulated as telephone companies are regulated. This is of significant concern to those municipalities that provide telephone service and depend on the revenue from that service as income.
