of VoIP Devices Net2Phone offers a full line of consumer and corporate hardware products for dial-up, broadband, single, and multiple user environments.
Net2Phone features solutions for locations that have high-speed Internet access (for example, cable, DSL, ISDN, T1/E1, or Wi-Fi). The Max series allows from four to thirty users to simultaneously make calls from standard phones, fax machines, or a PBX system. When used in conjunction with the
Voice Director, corporations can make free calls within their network, plus low-cost long distance calls to any phone in the world. With the Max ABS software, you can set your own rates and generate detailed bills for calls made through Max products.
Devices 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.
is VoIP Internet Voice VoIP stands for Voice over Internet Protocol. As the term says VoIP tries to let go voice
through IP packets and, in definitive through Internet. VoIP can use accelerating hardware to achieve this purpose and can also be used in a PC environment.
VoIP allows you to make telephone calls using a computer network, over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you'll hear a dial tone and dial just as you always have. VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone.
The Certicom Security for VoIP Securing VoIP networks today is about more than securing the signaling and media channels
it is also about securing the VoIP device itself.
As more and more connected devices are deployed, it is becoming increasingly important to have the ability to remotely provision and configure those devices, and to remotely update software in devices deployed throughout the network. These software updates need to be protected, not just while in transit but also to ensure that the update received by the device came from a reliable source, and is free from malicious elements.
of 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.
Ordinary phone to VoIP Devices The device lets users make and receive both Internet and traditional calls on an ordinary telephone using their existing broadband Internet connection along with their standard telephone service. There are no monthly fees, and no fees whatsoever for Internet-based VoIP calls.
No computer is required. The device has three connectors: one connects to the broadband Internet service (via Ethernet); one connects to user's standard telephone service; and the third connector goes to the user's ordinary telephone.
Client devices The new enhancements to Windows CE .NET include a sample Telephony User Interface (TUI), a comprehensive VoIP Application Interface Layer (VAIL) and Enterprise Infrastructure Integration services. Microsoft also announced that leading global original device and equipment manufacturers are developing VoIP devices using Windows CE .NET. Manufacturers include BCM Computers Co. Ltd., Casio Computer Company Ltd., Hitachi Ltd., NEC Infrontia Corp., Samsung Electronics, Symbol Technologies Inc. and Tatung Co. In addition, industry-leading silicon vendors, including Advanced Micro Devices Inc. (AMD), ARM Ltd., Broadcom Corp., Conexant Systems Inc., Intel Corp., MIPS Technologies Inc. and Texas Instruments Inc., are optimizing their CPUs and building reference designs for VoIP devices running Windows CE .NET.
VoIP is creating new opportunities for the communications industry to offer greater convenience and productivity to its customers," said Todd Warren, general manager of the Embedded and Appliance Platforms Group at Microsoft.
Devices for IP Telephony The standalone mta 3328re with 1 or 2 voice ports is an ideal solution for broadband service providers looking to deploy new
generating telephony services to their customers. Compatible with any standard analog telephone set, the mta 3328re delivers voice quality and features equivalent or superior to those of pstn. Its versatile and open system interfaces provide the flexibility to work with many different
networks and broadband access devices. The built-in nat& dhcp server functionalities of the mta 3328re makes it the ideal networking solution for the home user or telecommuter. The mta 3328re allows users to share their broadband connection throughout their home network by either connecting a pc or a hub into the mta downlink port.
to phone VoIP Devices USB Phones are quickly becoming the most popular VoIP device for PC to Phone users. Low cost and ease of use combined with the familiar layout of a conventional telephone handset contributes to the USB phones' popularity.
USB phones are quite simple. They are essentially an integrated speaker, microphone and keypad which interfaces with your computer via a vacant USB port. USB VoIP phones typically resemble their conventional telephone handset counterparts and function in much the same way.
The main drawback associated with USB VoIP phones is that your computer needs to be turned 'on' in order for the USB handset to function.
