A business IP phone system is nothing new, but it is still the best telecommunications technology available on the market. Instead of plugging into the standard network, these devices use an internet connection to package voice data and send it to other parties. They are fairly easy to set up, but a professional should still be called in to get the job done, as a bum network can cause many problems.
This setup can include either software loaded up on a computer or tablet, or a traditional handset that is internet capable. The former is typically used for simple peer to peer communication, and is not the best choice for fast moving companies. For these organizations, handsets connected to the network are best, because they are intuitive to use and come with several handy features. A business IP phone system is preferred over the traditional PSTN models because it is extremely flexible and inexpensive. Calls over the internet can be done for pennies on the dollar, and a customer can be transferred to any internet-ready device.
Handsets like the ones put out by Amtel are easy to use, as they come with handy graphical interfaces that can store customer contacts and run third party applications.
They devices are much like any other tool that connects to the internet. It plugs into the network using an Ethernet cable, and can be jacked directly into the router if needed. The model has all of the hardware needed to make and maintain the call onboard. While it is generally simple to set up, a professional should configure the network, as messing up the process can leave security holes that data can be funneled through.
