Wireless and VOIP Security Synergy

Recently, various broadband service providers are increasingly offering VoIP services to their users, including ordinary consumers and business users. If the previous provision of such services is in the process of trial and trial, then the real acceleration has now begun. As the integration and acquisitions between the network and traditional voice service providers are completed, the trend of acceleration will be maintained and even faster. Many broadband services are now increasingly being built around VoIP, and many experts believe that future VoIP will be the primary means of providing voice services, from the architecture of web development. However, there are still many problems in VoIP domain: How to connect the public alarm system, how to provide emergency service, how to deal with the power problem. Another key issue is how to achieve the distributed deployment of VoIP in the home and enterprise. Most existing VoIP service providers recommend that users use a cordless phone system to handle VoIP phone distribution issues. This kind of practice problem is many, the specialized organization tests many multi-channel, the pots telephone, but the use effect is not ideal. In fact, there is already a system that is good for implementing these operations and for better VoIP distribution: Wi-Fi wireless networks. For users, what is the reason to build a second wireless infrastructure for voice in the home once they find out that the existing Wi-Fi network can do the job successfully? Companies and web makers have begun to take action. Companies such as UTStarcom and ZyXEL have been launching Vowi-fi phones for more than a year now, and both products are performing well in terms of signal transmission performance and versatility. However, there are a number of issues that need to be addressed before users can use VoIP to eliminate all traditional telephony systems. In fact, the current VoIP system requires more configuration and integration than enterprise users, especially many small businesses, can tolerate. It may be that the IP voice system is running in these enterprises and running well, but once the user is required to process the Service Set Identifier (SSID) and encryption key to make their IP phone more secure, vendors will soon find that they are losing these users. Because it's not easy for users to set up and use Wi-Fi on their PCs, it's more complicated to do this on a tiny phone keypad. Security is also a key issue. Corporate users have good reason to lock their Wi-Fi networks to prevent their wireless network service accounts from being embezzled. Security is not only good for end users, the service provider does not want users to illegally access neighbors unprotected access points and use their devices to make VoIP calls. In addition, the security of the call itself is also a problem, the user authentication/service delivery and the actual call data security is the operator must care about. Finally, Vowi-fi also encounters performance problems, just as users are usingToday's Wi-Fi applications like that. Although 802.11e devices will soon be on the market, today's products do not provide any real QoS mechanisms. As a service provider, you can wait and wait for access points, telephones, and routers that are used by small businesses and ordinary consumers to meet new technical standards. A more positive approach, of course, would be to adopt a more initiative. Recently, Intoto company, which developed the software for Wi-Fi routers and residential gateways, talked about how they adapted to the second approach. They will be able to solve the above vowi-fi problems of the software installed in the residential gateway platform, do not need to make major changes to the hardware itself. The use of this approach has two elements. First, a residential gateway or wireless router uses two ssid-for a traditional data network, and another hidden SSID is used only for Wi-Fi phones. The phone itself is shipped with a second SSID, providing an "out-of-the-box" solution for end users. Security is combined with Wi-Fi security (WEP or WPA) and is handled by using a telephone with an IPSec VPN connection between the SoftSwitch or gateways of a service provider-thereby providing security for providers (authentication and call control data) and for users (voice pack security). Finally, packet priority technology must be adopted in residential gateway or wireless router. This technology, coupled with the telephone's virtual isolation Wi-Fi network, prevents interference with those very important phone calls. This approach enables VOWI-FI to become a viable, attractive service provider solution that makes it easy for a provider to reduce the time it takes to reconfigure a pots line in a user's home or office while providing a truly differentiated product.
