In our daily lives, we need a medium for communication. Mostly we communicate verbally, and sometimes through emails, and messages. We use cell phones, and telephones to communicate with our friends, and family members. One latest invention in the field of communication devices is an IP phone. An IP phone is known by different names like soft phone, SIP phone, or VoIP phone.

An IP phone works on Voice over Internet Protocol (VoIP) communication channel. It needs internet connection to work, and does not have any link to public switched telephone network. The calls can be made at any part around the globe from a computer over the internet. IP phones convert voice into digital signals, and vice versa. It looks pretty much like an ordinary phone, or a cordless phone, but it only works when it is connected to sound card of the personal computer, or laptop.

The hardware components of the IP telephone include speaker, ear phone or microphone for receiving and delivering voice messages. It possesses ADC and DAC converter for the exchange of voice and digital messages. The other essentials include general purpose processor, Ethernet network hardware and voice engines. The most commonly used power sources are batteries and direct current sources. It requires no separate wiring.

There is a direct connection of the IP phone with the router. Once you are connected with the router, then you are connected with the information-sharing network. All this is done with the help of the voice over internet protocol software. This software is very easily available; it can either be downloaded free, or can be bought for a small amount of money. With the help of an ATA adapter, you can easily convert an ordinary phone into an IP phone. The adapter works by taking the simple analogue signal, and converts it into the digital signal for its provision to the other end, over the internet.

An IP phone has loads of other features that make it an ideal choice for any business firm. The call management features are convenient, and cheap than the regular phone systems. Though different IP phones have different features, and functionalities but most phone have features like call waiting, call forwarding, call blocking, fax, local number portability, three way calling, CLI, and voice mail facility.

The reason of popularity of IP phones is its convenience to call at any part of the world. They are perfect means of communication with the friends and family members over the internet channel. The calls between computers are free, but you have to pay for calls made on landlines, or mobiles, however, the rates are very low as compared to calling from regular phones. For making calls you only need an internet connection from any internet service provider (ISP).

On a simple telephonic conversation, only two persons can chat. With an IP phone, on the other hand, you can set a conference call. Thus, you can make extensions, and more than one call can be handled on one access line. It utilizes the compressed bandwidth that makes the transmission continuous and fool proof.

The portable nature of IP phone greatly increases its popularity. Staying at home, you can access your office or organisation through your IP phone. You can also customise an auto-attendant. All local and international calls can easily be diverted using IP technology.

So, IP phone technology is a revolutionary technology that has all the qualities of a sophisticated phone system. It makes your small business impressive and your life easier than ever before.
