Magic Jack spoker is your one stop resource for your VOIP and Magic Jack Needs. Understanding how Magic Jack works now becomes a much simpler task when you take into account the fact that it works just like any other VoIP service provider when you use the computer microphone and speakers to make telephone calls.

Magic jack is a USB based device which allows you to make calls over the internet using a normal telephone handset, or just a microphone and speaker connected to your host computer. It is a computer peripheral. Wikipedia defines a peripheral as a device attached to a host computer but not part of it whose primary functionality is dependent upon the host, and can therefore be considered as expanding the host's capabilities, while not forming part of the system's core architecture. Basically a device connected to the computer, like a printer, speakers, scanners etc. which adds to the capabilities of the computer.Understanding how it works now becomes a much simpler task when you take into account the fact that it works just like any other VoIP service provider when you use the computer microphone and speakers to make telephone calls.
Magic Jack spoker is your one stop resource for your VOIP and Magic Jack Needs.The Magic Jack is such a USB device, which, when used in combination with a telephone communications network as is provided by the YMAX corporation provides Voice over Internet Protocol (VoIP) service to users in Canada and the United States. Voice over Internet Protocol is the term used for transmission of voice and audio over the internet in the form of packet data as opposed to the conventional public switched telephone network (PSTN). The analog signal is first converted to a digital signal, compressed and sent over the internet as packet data to the receiver,
where it is decoded back to an analog signal. This is the basic principle of VoIP.
Understanding how it works now becomes a much simpler task when you take into account the fact that it works just like any other VoIP service provider when you use the computer microphone and speakers to make telephone calls. The one radically different feature which separates this device from other similar VoIP services is the use of a regular telephone handset to make telephone calls over the internet.
Nonetheless, with technology being what it is today, understanding how this device works with a conventional telephone handset isn't very difficult either. An electronic circuit called a SLIC or subscriber line interface makes this possible. SLIC is a modular electronic circuit printed on a PCB (printed circuit board) which interfaces the subscribers of Magic Jack to the rest of the telecommunications access network. In this case, the SLIC interfaces the POTS i.e. the plain old telephone service to the proprietary Magic Jack VoIP network. So while the POTS is not able to undertake analog to digital conversions and vice versa, the VoIP service is capable of this conversion.
With the help of this technology, you can interface your telephone handset and its analog signals to the internet packet data carrier enabling you to carry out telephone conversations over the internet using a high speed broadband connection only. This should help you understand how this device works. The technology is complicated, but its working is fairly simple, although definitely not as easy as Magic Jack is to use.
