is another service available for which you don't need a computer except for
initial set up/ .
The diagram given below is self explanatory.
There are many VOIP providers in India.
Basic requirement:
1.An Internet connection Broadband
2.An adsl Modem
3. A VOIP router ( provider by the company or other s like Linksys)
4.And one or two phones of course!
5. Computer will be usually available with most.
