Is VOIP Replacing PSTN
VOIP technology was in existence for the past few decades, but only recently, the technology has gained so much importance. The need to make long distance calls increased in all offices and VOIP made it possible at low prices. The added advantage of integration of VOIP to existing telephone networks has increased the usage of VOIP in homes and offices. Today there are no offices that lack VOIP services. Now, with the introduction of VOIP, many users are using it, but the traditional PSTN is also in existence. VOIP coexists with PSTN as of now, but in the future, experts say that VOIP will overrule PSTN because of the ubiquitous ability of VOIP service.
PSTN networks have their own advantages and disadvantages. The well established technology makes PSTN systems more reliable. A dedicated line is established between the caller and the called party in the case of public switched telephone networks. This dedicated line ensures more reliability and chances of call dropping is almost nil with PSTN networks. Further, the set up process is hassle fee and usage procedures are simple for consumers. However, efficient use of bandwidth is limited with PSTN network. Most of the bandwidth dedicated to PSTN remains idle most of the time. The monthly fees and high call charges restrain the users to use PSTN telephones. PSTN networks can handle only voice data and they are transmitted using fixed cables.
VOIP on the other hand solves most PSTN problems, but the ubiquitous technology has its own limitations. There are no monthly fees in the case of VOIP and you have to pay for the number of calls you make. Prepaid cards allow you to use the same device in different countries without any change. The data sent through the network is compressed, allowing optimal utilization of bandwidth. VOIP primarily uses internet to transfer voice. Further, voice is also sent as data packets. This simplicity has reduced the cost of every call. Many value added services can be given to the users at lower cost. VOIP allows you to make use of soft phone and virtual keypad without even using telephone system if you have a broadband internet connection. The only problem with VOIP is related to call quality. When you choose a good service provider, you can overcome this problem. With a good service provider, you can achieve call quality equal to that of PSTN networks.
In the offices and homes, the usage of internet has increased. Further, data traffic is much higher than voice traffic. The existing system can handle both data and voice traffic in an efficient way, but this cannot be called the optimal system. Studies show that data traffic will continue to increase in the near future. Moreover, the availability of internet facilities using wireless networks has motivated the researchers to improvise the present VOIP technology. With more and more improvements, VOIP technology can completely replace PSTN service, but it will take at least a few decades. For now, you can save money without compromising the services, using hybrid VOIP and PSTN systems.

Absolutely agreed! VOIP will totally replace PSTN in near future and with traditional phone companies moving to VOIP the change is evident. It just needs easier regulations and most importantly a good 911 support.

Voip does have a lot of advantages over regular phone lines. In business i do see it as the main phone service but some companies might have a landline as a backup in case thier are any problems. Home phone lines are being droped for cellular more than voip but thier are alot more people using voip now than ever before at home.

How much cheaper is it to call abroad compared to a regular phone? For example if I was to call australia from the UK for 10 minutes roughly how much would I save?
I’ve been considering switching to VoIP but haven’t yet.

I think that VOIP is so much better than regular phone lines, and I have been using it for my business for quite some time.

I don’t think PSTN can replace VOIP, i have been using VOIP for a year now and I can say that it is much better than the others. Just my opinion.

I think it’s VOIP who will replace PSTN. And you know what? I suppose soon our cell phone providers will stop providing us with GMS. Soon we will be provided with just good internet because we’ll need only that.

Everybody from small business owners to major corporations and not to mention households worldwide are starting to see the benefits of VoIP. VoIP saves money and cost efficient. Whether you’re using VoIP for your residence or your business, you’ll find it to be a lot cheaper than your normal landline telephone cost, be it short or long distance calls. However, the cost varies from one voip provider to another. Some allow unlimited calls and some charges only a small fee.
