As the internet dominates the communication world by a bigger margin than any other tool, it has eaten its way into one of the most conventional methods of communication: the telephone. Traditional telephones are fast going obsolete as internet based phones (known as VOIP Phone Systems) are taking the center stage. If you are a tech savvy person who is interested in the latest trends in the world of electronic devices, then the idea must appeal to you. We came up with a list of ways in which Internet phones are distinct from Normal Phones.
VOIP phone Vs. PSTN
Traditional telephones operate on a protocol named PSTN, or Public Switch Telephone Network. This is largely a means of analogue communication which means that the conversation you have over the phone is not recorded or stored at any point. Also, the sound is transferred from one point to another in an analogue circuit. This is why answering machines have to manually record the conversation you have when you are not present.
On the other hand, digital communications involve transferring the content of a conversation into digital sound, thereby making it imperceptible by a sequence of bits or binary numbers. This sequence is then transferred by the TCP/IP (Transmission Control Protocol/Internet Protocol) which is commonly known as the internet. Note that VOIP phone is not only hardware based phones that look like the conventional telephone. Most “soft-phones” is also VOIP Phone. The most common example of such phones is Skype. It is software that allows you to call other computers using a Voice over Internet Protocol device. Such devices can also be hardware encrypted with the sole purpose of performing one operation.
SIP/SCCP Vs. PSTN
Your local telephone company has the control over the area’s PSTN networks. They charge you a certain amount of money in exchange of allowing you to use this service, whereas VOIP phone operated by using the internet for connectivity. Therefore, it incurs only the nominal fee of having an internet connection at home, which everybody does these days. Other than the internet, you have to get a SIP subscription which costs next to nothing for voice calls within a country and less than a cent per minute for abroad. Therefore, VOIP Phone is cheaper than analogue phones. This is why they find extensive use in call centres.
A typical phone line, when used at home, costs anything from $35 to $100 depending on how much it is used. On the other hand, VOIP Phone will only use the internet for connecting you to the rest of the world. This makes them cost much lesser. If you are a person who likes to save money in the long run rather than instantaneously, then this kind of phone is for you. You can see some examples here at sipply.ca
There can also be VOIP Phone that integrate and operate also as analogue phones. Some phones can be connected to computers using USB ports. The options are endless.
