Voice over Internet Telephony isn't widely used in office networks, let alone in the home, however if you make international phone calls then you are probably being routed through IP infrastructure because of the lower costs of calls. What this does mean, though, is that the infrastructure is quite obviously already in place and anyone who chooses can do so easily. This means that you can 'call' friends, family or associates using your own VoIP without the need for them to have the same technology installed. The costs are phone calls that are reduced dramatically by using SIP Did for VoIP and once the infrastructure is in place there are usually little or no additional infrastructure charges required making it a cost effective and affordable telephony solution. Because VoIP is a new technology you get the usual advantages of employing a new technology; increased technological advances and new technologies are employed meaning you get a state of the art system. Telecommunications providers have been regularly using IP networks to transfer voice data and so most of the teething problems have been thoroughly investigated and ironed out and all the advancements made have been integrated into a system you can have installed in your home, office or business.

Does Voice Over IP Telephony Spell the End for Traditional Telephones?

VoIP, as a technology, is still in it's infancy and new developments are being found every day. However, there are limitations to the service and the technology which need to be addresses before it can become a complete replacement for your standard phone line. Because the Internet knows no geographic boundaries it means that, for example, calling the emergency services would not necessarily put you through to your local emergency dispatch centre. In addition, you can't send or receive faxes and you can't route traditional modems, alarm systems or satellite systems through your VoIP connection, because they require access to a voice grade phone line. For the moment VoIP is a compliment to your traditional phone line, rather than a replacement, until these problems can be ironed out. The advantages of VoIP are still significant for homes and business users alike. Big businesses are already saving substantial money by installing IP networks and using VoIP protocol to transfer voice data. This essentially makes the calls themselves free, only having to pay for the Internet connection and the monthly VoIP fee.
