VOICE OVER INTERNET PROTOCOL

VOIP basically are the communication protocols,technologies,etc.., which are involved in the delivery of voice communications and multimedia sessions over internet protocols, such as the internet.The VOIP has been in a process of improvement and today has become quite effective and useful in our personal and professional lives.Early VOIP providers offered business models that were a reflection of the architecture of the legacy telephone network.Later the second generation providers such as the 'SKYPE' had built closed networks for private user bases which offered the benefit of free calls and convenience.But, the biggest disadvantage in this protocol is the inability to call out to the other networks.While the third generation, such as the 'google talk' have adopted the concept of federated VOIP.This concept is completely different from the first generation and has completely stopped the architecture of the legacy networks coming in to play.

Today, VOIP is being used regularly by the telecommunication providers as they use VOIP telephony technology over the dedicated and Public Internet Protocol networks for connecting the switching centers and also to connect the other telephony network providers with themselves.This is also called as the Internet Protocol 'back haul'..

Certainly there are more advantages over the disadvantages of this VOIP that it has come into use.Few advantages can be identified as below:
1.The arbitrary and dynamic interconnection between any two domains is made possible whenever,the user is willing to place a call.
2.VOIP is available in the smart phones and internet devices.Using this facility, the users of portable devices that do not have the calling and messaging facilities can make calls or send text messages over 3G or Wi-Fi conveniently.
3.Due to the bandwidth efficiency, the VOIP can provide its services to the business houses at a very low cost.This has prompted the businesses to shift from the old copper wire telephone systems to VOIP to save their monthly expenditure on the phone costs.

4. VOIP enables the user to run both voice and data communications on a single network, which significantly reduces the infrastructure costs.
5.The price of extension is relatively cheaper when compared to the PBX.The VOIP switches may run on the hardware like the PC's or the Linux systems.They rely on standard interfaces rather than closed architectures.
6.The VOIP has summed the communication services that visualize all the communication means such as the phone calls,fax,voice-mails,web conferences,e-mail,etc...., as non-similar and different units that can all be delivered by any means and to gadgets,including the cellphones.
7.VOIP consists of simple and intuitive user interfaces, this allows the user to make simple configuration adjustments and changes.Maintenance becomes easier as there are not many devices to look after.
8.The second generation VOIP like the 'SKYPE' has also begun to target the business houses by providing the facility of free connections between the users on the their network.
9.The international calls using VOIP do not cost much.
10.In addition to this, the true VOIP enables subscribers to call one another at zero cost.
11.This VOIP, restricts the need for separate voice and data networks as the phone calls are routed over the existing data networks itself.
12.Finally,its ability to accommodate more than one telephone call in a single broadband connection.

With over a dozen uses of this VOIP,It has become one of most irresistible connecting protocol all over the globe.The cost efficiency has attracted the business houses to it.
