Voice Over Internet Protocol(Voip) - Information

voip, VOIP, voice over internet protocol, tricky tricks, viber technology

DO YOU KNOW YOU USE VOIP TECHNOLOGY ?
Yes, here's how
Do you use application like Viber, Wechat or Line Or Skype ?
If yes then you already use the VOIP technology.


If NO then have you made any international call. Well when you make international call then companies use the same technology as Voip.

It is stated as the technology of future. Voice Over Internet Protocol is one of the technology which is used for voice communicating(phone calls) through internet as per some protocol world wide. Well even I think that this technology will be the technology which we all will be using near future.
Voip read as "voip" or "V.O.I.P" or "Voice Over I.P" is the one and the same. Voip is defined in Wikipedia as "Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet."

Its confusing well to understand Voip one must understand first its working.

HOW VOIP WORKS ?
Voip is used to make voice calls . When we speak the voice is taken in analog signals and then converted into digital signals later sent over the internet again converted back into analog signals and we are able to hear it back. The conversion is done by a device called as ATA used read as "ata".

Data is converted as Digital data and this digital data is further cut down in small parts called as packets which are sent over the internet.
Again this packets are decoded into digital data and later converted back in analog signals. All this happens in just matters of seconds in any part of the world.

There are some companies which offer voip service.

VOIP CONNECTIONS
1. Voip to Voip connection (Direct connection) : Here special phones are made only for voip purpose.ATA is not required.
2. Traditional phones to Traditional phones : Here old phones are used which we use in the olden days. Here ATA is used.
3. Traditional phones to Voip connection (vice versa) : Here on one side an old phones is there and other side the Voip purpose phones are there.
4. Computer (software) to Computer (software) via Voip. : The latest in voip technology where computers are used and with the use of microphone and webcam,
 calls as well as video call can be made.

WHAT ARE THE ADVANTAGES ?
1.Voip is cheap it saves Money..!!!
For voip connection you need a normal telephone instrument,
ATA converter(which is sometimes offered free by the company providing service).A good internet connection. Even 512 kbps internet will work good.
If using computer then no more things to add just Headphones with a microphone. For video calling you even need a webcam.
That’s all !

2. No need of techie knowledge.
Using voip technology phones is same as using normal phones.

3. Making international calls and local calls is almost of same price and requires no more extra charges.

4. Extra features. such as video calls, you can even send images, sounds, music etc

5. Where ever you go, you can talk through your phone where ever you find a internet connection. So it has mobility, it is mobile.

6. Considering digital communication uses the same wire which we use
To transfer multiple data.
So installing voip communication is cheap

7.When we make international calls,  this companies use the same technology of voip and charges us more.

Voip is the technology which would replace all the traditional telephones and communication technique.

So why not start using it now.

WHAT ARE THE DISADVANTAGES ?
1. Full Dependent on the internet.  If the internet goes down then voip will also be DOWN.

2. Your traditional phone works on wall power (i.e. the power provided by central office directly.) If your electricity goes down then your phone will also go down. Cordless Voip phones will work but  irrespective of electricity internet will not. So its one and the same.

3. Many of the systems in our house are integrated with the telephone line. (eg. Digital video recorders, digital subscription TV services & home security systems).  So this all things cannot be used with voip. Until all these industry comes together and make a product which works with voip.

4. VoIP is susceptible to worms, viruses and hacking, although this is very rare & VoIP developers are working on VoIP encryption to counter this.

5. Processor power is important . Imagine you talking on phone and decide to use your computer so more processing is needed this might lead to get your System hang, or worst of all your system will crash. ?

CONCLUSION
 Still voip is the technology which will overcome all the traditional phones.

More new companies are coming in and providing voip services which later on
Increases competition and will benefit the users.

Companies only charge some amount and various offers are also given.
Even possibility that we can make free calls overall.

Voip is now available on smart phones with proper mobile internet connection.
Everyone can use this technology.
