Patent number: 7061901Abstract: An adapter is disclosed which allows attachment of a standard telephone to a computer as a standard peripheral. The adapter converts analog signals of the telephone to digital signals of the computer and vice versa. The adapter can also be a stand-alone device allowing the telephone to be attached to a computer network. The adapter, in this case, contains the computing power to support the necessary data network protocols, and PSTN signalling protocols. In this way voice communication is enabled over a computer network without requiring the computers to be equipped with sound cards.Type: GrantFiled: September 7, 1999Date of Patent: June 13, 2006Assignee: Way2Call Communications Ltd.Inventors: Shimon Shnitzer, Ronen Hchman, Shlomo Tsurri, Doron Shahar
