Broadband telephony
Broadband Telephony is the utilisation of broadband connections to deliver voice calls. Typically, services are hosted, meaning customers enjoy traditional phone functionality without the need to purchase a phone system at all. Calls are transmitted as IP Packets to the host company, where they either 'break out' to the public networks, or continue as IP calls across the Internet.
Due to the utilisation of Voice over IP, calls can be delivered across the internet for free in some circumstances.
