Generally, telephone service via residential VoIP is
either free or costs less than similar service from traditional sources, but
it's 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 where users have accessible underutilized
network facility they can use for residential VoIP at no extra cost. VoIP to
VoIP telephone calls on any given provider are customarily free, while VoIP
to PSTN calls normally costs the user of residential VoIP.
VoIP technology does not quite require broadband Internet
access, but this normally sustains improved quality of service. A
considerable percentage of homes today are connected to the Internet through
DSL, which requires a traditional landline telephone line. Having to pay for
provider residential VoIP as well as both a basic landline telephone line
and broadband Internet access minimizes the probable benefits of VoIP.

Can I call using the internet connection?
After its introduction, Internet telephony has been highly developed
rapidly in a brief period. Many software developers currently offer PC
telephony software. However, more importantly, gateway servers are rising to
act as an interface between the Internet and the PSTN (It expands as Public
Switched Telephone Network). With voice-processing cards, these gateway
servers allow Internet telephony VoIP(It expands as Voice Over Internet
protocol) users to communicate through traditional telephones over long
distances without exceeding "Long Distance" telephone network.
A telephone call travels from the local PSTN to the
nearest gateway server, which digitizes the traditional, analog voice
signal, converts it into IP packets, and moves it to the Internet for
transport to a gateway server at the receiving end. This server alters the
digital IP signal back to analog and concludes the call locally. With its
Internet telephony support for computer-to-telephone calls,
telephone-to-computer calls and telephone-to-telephone calls, Internet
telephony VoIP represents a vital step toward the merging of voice and data
networks.
