PSTN vs VOIP

PSTN (Public Switched Telephone Network) also known as POTS (Public Old Telephone Service) vs VOIP (Voice Ove Internet Protocol)....

First and foremost about this comparison, this particular post is purely, in regards on what I know and understand about PSTN and VOIP...

PSTN is the type of telephone service that we're been using for ages, our local phone company provide this service and they are the one who provide us the telephone number depending on what area they cater and if there is another telephone provider on the area, we can simply switch to a diferent telephone company together with our existing telephone number...but to some areas that is not possible, basically it depends on the law of the certain region or country regarding telephone service...

Basically PSTN is a telephone service where in it required copper wires to be connected to the network and it stays with one place, meaning in a certain residence or building, Cellphone is also a form of PSTN because it receive signal and it works the same as a land phone...all I know "PSTN is a kind of service that need to stay in one place and need to be wired connected and with mobile phone you can receive and transmit signal"....

As I remember before, in order for us to have internet service we need to have a land phone so we can connect using our modem, it could be dial up or DSL...Now Internet service have changed, you can now have internet service with your curent telephone provider without the presence of telephone line, meaning they can provide you a stand alone DSL, like cable company does, that if you have cable TV service with them they can also provide you Cable internet service...Our technology nowadays is really amazing....

Even before internet service has been upgraded to different type service, or how you want it, because like what I have said, it could be DSL with phone line, Stand alone DSL that does not required telephone service, Cable internet service, etc....VOIP is already there....

VOIP, nowaday is very popular, having VOIP phone at home is a good, because this way around you don't need to have telephone to have internet. Now you can have telephone service using the internet...VOIP basically is a form of communication using the internet, its just that now they provide you a number (telephone number) and it's great.

If you notice, voice chat is also a form of VOIP, its just so happen that with this you are using the IP address and you dont have telephone adapter to connect....hehehehe

Here is the good part, VOIP is less expensive, and you can carry your phone number anywhere in the world as long as you can access an internet service and not worry about paying high international calling rates, but be reminded that not all VOIP company provide a telephone adapter that you can take anywhere....If your VOIP company can provide yu a portable telephone adapter, imagine if you have familis in a differnet country, you can get them a separate telephone number on a different phone adapter and it will be VOIP to VOIP call for both of you and not to worry paying per minute rate at all.....

With PSTN, you pay for every feature that you need and with VOIP they provide you all the feature whether you need or not with no additional charge....

VOIP is good but there is also disadvantages of having VOIP, if you don't have high speed internet service, you cannot used VOIP, if your alarm system is not compatible with VOIP service, you will end up with no alarm system, but there is Alarm system company who can do that...Another thing, if there is no power and if your internet service is down, you can't use the phone because there will be no dial tone...

Yes you are correct, there are disadvantages, but let see the advantages, it's unlimited local and long distance, especially to residence of USA, Canada and some other countries, and you can take it with you once you move out or having a vacation at anytime...when you move you dont have worry paying for moving a line fee, no additional Long Diatance calling plan rate, and you can always have a mobile phone for a back up....that is what everybody does now....

I just hope that I was able to provide you an informative ideas about this......
