What is VOIP ?

Many of them keep wondering What is VoIP? VoIP expands as Voice over Internet Protocol. The routing of voice conversations over the Internet or other IP-based networks like IP Telephony, Internet telephony, Broadband Phone, Broadband telephony and Voice over Broadband is known as VOIP.

The protocols used to transmit voice signals over the IP network are normally referred as Voice over IP. These Voice over protocols are usually observed as commercial insights of the experimental "Network Voice Protocol" invented in 1973.

Voice over IP traffic can be installed on any IP network, which includes those deficient of a connection to the rest of the Internet, for example on a local area network.

What is VoIP? Generally, telephone service via VoIP is either free or costs less than similar service from traditional sources, but comparable to alternative Public Switched Telephone Network (PSTN) service providers. Some cost savings are from using a single network to convey voice and data, especially when users have accessible underutilized network facility which they can use for VoIP at no extra cost. VoIP to VoIP phone calls on any given provider are cu stomarily free, while VoIP to PSTN calls normally costs the user. In that case VoIP charges have to be borne by the user..

A VoIP tutorial will teach you that VoIP can facilitate responsibilities that may be difficult to pull off using traditional telephone networks:

* Incoming telephone calls can be instantly routed to your VoIP telephone, no matter where you are connected to the network or not. You can take your VoIP telephone with you on a trip. Wherever you connect to the Internet, you can automatically receive incoming telephone calls.
* No-cost telephone numbers for use with VoIP are available in USA, UK and other nations from organizations, such as VoIP User.
* The call-center agents using VoIP telephones can work from anywhere with a suitably fast Internet connection.
* Many VoIP packages include PSTN features that most telephone companies regularly charge extra for or may be unavailable from your local telephone company. This includes 3-way calling, call forwardi ng, automatic redial, and caller-ID.

These are the functionalities in the basics of VoIP.

A VoIP tutorial will also show you that VoIP allows users to travel anywhere on the globe, and still make and receive telephone calls:

* Subscribers of telephone-line replacement services can make and receive local telephone calls regardless of location. For example, if a user has a Philadelphia telephone number and is traveling in Africa, and someone calls the telephone number, it will ring in Africa. Similarly, if a call is made from Africa to Philadelphia, it will be treated as a local telephone call. Of course, there must be a connection to the Internet, WiFi for example. Only then this will work properly..
* Users of Instant Messenger-based VoIP services can travel anywhere in the world as they make and receive telephone calls.
* VoIP telephones can assimilate similar services available over the Internet. This includes video conversation, data file or message exchange in corre spondence with conversation, audio conferencing managing address books and sending information regarding availability to concerned parties.

This is the mobility aspect of basics of VoIP.
Processes involved in VoIP
Two types exist of PSTN to Voice IP services. They are DID (Direct Inward Dialing) and access numbers. DID usually connect the caller directly to the VoIP user . In the case of an access number they require the caller to key in the extension number of VoIP user. Access numbers are usually charged as a local call to the caller and at no-cost to the Voice IP user.. DID normally has a monthly fee. There is also DID that is free to the VoIP user. It is certainly chargeable to the caller.

VoIP technology still has a few limitations that have caused some to believe that it is not prepared for prevalent deployment. Caller ID support among VoIP providers greatly varies. When calling a PSTN number from VoIP providers, Caller ID jisn't supported. The contact will not know who is calling. The number is displayed as 'Unknown' or '000-012-3456'.

In several cases, VoIP providers may permit a caller to spoof the Caller ID information, making it seem that they are calling from a different number. Further information can be found in VoIP tutorials.

One drawback is the failure to send faxes because of software and networking limitations. Another drawback is the inability to make telephone calls during a power outage. Re-wiring is necessary to use telephone jacks in the average house. If Voice IP is used in solitary LAN (with no internet connection), then it would utilize more resources . These will be equal to PABX.
