VoIP Devices

  1. VoIP with RJ11 Connector devices
    The IPO-11 is a USB VoIP device that has a RJ11 connector for regular RJ11 telephones. Its regular telephone interface with DTMF decoding allows you to make internet calls using the keypad of your regular telephone. Its full duplex audio, and echo cancellation have made it the ideal VoIP device for you. Best of all, place PC to PC, and PC to phone calls over the internet saves users up to 95% off the current long distance rate, while at the same time maintain, if not exceed, the audio quality of regular phone. Once you connect your USB VoIP Series to the computer and the Internet, you will be able to make long distance calls to any phone in the world at great savings, while making global calls to any PC for the cost of your Internet access.

  2. Windows-powered VoIP Devices
    This section of the Windows Devices Showcase focuses on Windows Embedded devices incorporating Voice over Internet Protocol (VoIP) capabilities. Devices utilizing VoIP technology include desk phones, desktop and laptop PCs, WAN- and WLAN-enabled handsets and PDAs, and various application-specific devices in which voice communication is an important feature, such as automotive telematics systems. The WebQ provides voice and video conference capabilities over the Internet, Public Telephone Network, or ISDN/ADSL lines. It runs Windows CE 3.0 on an x86 processor. It also incorporates a white board function that lets users exchange memos and drawings.

  3. VoIP Device
    Many people around the world are discovering the cost savings available with Voice over Internet Protocol (VoIP) telephony. VoIP uses the Internet to carry telephone calls, bypassing the public telephone network (PSTN) for local and long distance calls. While VoIP once required that there be a computer on both ends of a conversation, modern VoIP communications simply require a VoIP device attached to a broadband Ethernet connection. A VoIP device may come in many different forms, but the principle of each is the same. Using sophisticated hardware and software, a VoIP device compresses the words you say into voice data packets that pass over the Internet. These voice data packets are then decoded at the other end, either by a gateway VoIP device connected to a PSTN or by the other party's VOIP device, so that the person you are calling can understand what you are saying. Most residential VoIP service providers offer their own VoIP device to their customers, free of charge or at a small cost. 

  4. Securing VoIP Devices
    Securing a Voice over IP (VoIP) network is a complex issue that involves many factors, including elements unique to each specific network configuration. As with any IP based network, VoIP systems are potential targets of many types of attacks. In this paper, we will discuss some of these attacks, and present mechanisms that the developer of a VoIP product can incorporate to make the device more secure. The list of potential threats to a VoIP system (or any IP system) is extensive, and new issues may be uncovered on an on-going basis. Just as there is no exhaustive list of potential threats to a VoIP system, there is no definitive solution for preventing someone from finding and exploiting a specific vulnerability.
