Internet telephony hardware
In order to use internet telephony one requires the appropriate hardware. Four different alternatives are available here. The first option is to use a standard computer with microphone for user voice capturing, as well as a loudspeaker or headphones in order to listen to the conversation participants. Added to this comes the application and installation of special software on the PC. Secondly, it is possible to use specific VoIP end devices as well as IP and SIP telephones. These only differ from a standard telephone in terms of the technology that enables the data transfer via the internet. As a further option it is possible to use the conventional telephone and connect this to a special adapter, which converts the analogue telephone data into digital signals. Finally, it is also possible to use a mobile phone by connecting through the telephone system via an FMC client. The advantage of the last three options lies in the operation of the device, which can be used in the same way as a conventional telephone.A further benefit is that the user is also attainable when the PC is switched off.
