Calling over the Internet telephony allows users to send and receive voice, video and images over a single IP network.

Providers of the VoIP termination services deliver carrier-class quality compared to traditional PSTN service providers. Without any geographical constraints, user are able to enjoy VoIP service anywhere and anytime. There are two types of call termination services namely switched termination service and dedicated termination service.

The dedicated long distance termination services have lower costs per minute due to the requirement of a dedicated DS1 - DS3 line to be installed. This is because there is still a fixed loop cost for the line depending upon the size.
