BroadVoice is a Voice over IP (VoIP) telephone service provider that enables customers to transmit / receive voice and video communications via a broadband Internet connection. Customers typically make and receive phone calls using an ordinary telephone connected to an analog telephony adapter or a digital SIP-enabled wired (Ethernet) or WiFi phone. Devices are either provided by BroadVoice, or customers may use their own equipment on discounted rate plans. Calls can be made to any telephone number in the US or internationally.
