Voice over IP, or VoIP, has revolutionized the way phone systems work. With VoIP, you have access to flexibility and features -- and for much less cost -- than traditional phone systems can provide. Let's take a look at some of the benefits and features of "VoIP for business" systems.

Cost effectiveness

The first thing you'll probably notice about using VoIP for business is that your phone bill will decrease substantially. With traditional systems, called "packet switched telephone network" or PSTN lines, time is literally money in that you pay for every minute you spend on the phone. That means if you have to make international calls especially, you're paying an awful lot to call long distance. VoIP is different. VoIP uses the Internet as its "telephone line." As long as you have broadband access, you pay a fixed amount for access, meaning that you can talk as much as you need to for one fixed rate.

Easily add multiple users "all at once"

With traditional phone systems only two people can speak at a time. However, VoIP for business changes that. With VoIP business systems, you can have conference calls with a whole team of people communicating in real-time. This is possible because VoIP uses data compression during transmission, meaning that the carrier (the Internet) can handle a lot more data than traditional phone lines can. Handle more calls on one access line, save money -- and be more efficient, too.

Equipment is much less expensive

Instead of installing lots of complicated equipment with the traditional phones, the Internet connection (VoIP) simply needs an online connection and necessary equipment (phone equipment, and/or headphones with sound card and software).

Lots of features with VoIP for business

Perhaps the best thing is that with VoIP business phone systems, you get lots of features included or at very low cost that would otherwise be fairly expensive with a traditional phone setup. For example, VoIP for business lets you make calls anywhere in the world with your account, and you can generally forward calls from your business phone to your cell phone easily so that you can be "connected" to your office even if you're not there. Caller ID, voicemail, and the ability to add extra virtual numbers as needed for colleagues are also usually included free or for a nominal fee with VoIP business phones.

Flexible network layout

With VoIP business phone systems, you have almost endless flexibility when you set up your network, and you can change it as you need to. With traditional systems, you have to determine a set up, put it in place, and then leave it. Changing it or expanding it can cost you a significant amount of time and money. However, network complexities are a thing of the past with VoIP, meaning that the infrastructure is incredibly flexible and can support not just voice communication, but Web conferencing (through wireless networks like WiFi, as well) and other forms of communication in addition. Many VoIP business phone systems offer consumers voicemail to e-mail capability, for example, for even greater flexibility.

When it comes to your small or large business phone system, VoIP offers all of the features you need to keep things running smoothly.
