Benefits
Cheap International rates: VOIP calls are known to be much cheaper than equivalent services offered by traditional phone companies. A single broadband network is used to carry both voice and data. This substantial cost saving occurs because the technology allows the network to carry several calls in the same amount of space that normally carries a single call in a traditional phone network. Also, the data is compressed allowing more space and thus, lower rates.

Convenience: It is easy to operate using one of two options:
Using a computer to make calls or,
Using a special broadband phone to make calls rather than a computer

Call centre on the move: Call centre agents can work easily from anywhere as long as they have a good Internet connection.
