VoIP Types
 
 

VoIP has gained in popularity in today’s world with both the individuals and businesses and can be a major competitor for the regular telephone. There are 3 major types of VoIP:

Consumer VoIP

Many consumer-oriented VoIP services offer cheap or free voice calling. This can be done through a particular adaptor connecting to broadband services or a program similar to telephone on a home computer. Consumer VoIP services are an economical method of dialing into the public telephony network. Most of the times, there are many great bargains available for you. Skype lets you talk to others free of cost. The major problem with these services is that their mode of use is not obvious as it is more difficult than the regular phone. Also if the computer is involved in heavy processing, the sound quality can be affected. Good quality headphones, microphones and speakers should be used to prevent the distortion of the sounds and eliminate feedback or background noise.

Small to medium sized company VoIP

"Centrex" is a phone service, used by many VoIP services. It carries out all the central call controls and switching is generally done inside a box on the wall and is the remote internet hosting center, in a central server. It is usually called as a "PBX" in the sky. Centrex services include telephones on the desks of the customers with connect out through broadband internet, to the PBX servers.

The benefits of this system are:

Easy deployment by just plugging the phones into the internet.
Lower costs as the phone service is carried out through the web.
Lower capital expenditure due to elimination of the phone switches.
Cheaper internal phone calls, especially between offices and employees in their homes (inter-site calls).
Different unique methods of working and flexibility like highly distributed offices and increased number of people opting to work from home.

Big business VoIP

This is the oldest aspect of the VoIP market and involves the interconnection between the normal office phone systems like the PBX and the different company sites. Most of the corporates use the phone systems from suppliers like Panasonic or Avaya. With the help of a VoIP adaptor or converter, these systems can be connected allowing calls to be routed across various company sites to be carried over the corporate internet connection (corporate VPN). The customer does not have to bear any extra costs.

Similarly, many new office phone systems are "IP enabled". They have multi-site connectivity with an inbuilt internet connection. The home-worker handsets can be linked to the head office PBX through the internet.

With many cost saving solutions for businesses being provided by vendors, due to rapid advances in technology, it makes sense to consider the different choices given by the equipment manufacturers.
