VoIP Telephone Adapters
A VoIP phone uses Voice over IP (Voice over Internet Protocol) technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (PSTN). An adapter connects VoIP telephones to other devices.
