Sip Voip Server

VoIP has a lot of security risks, face a lot of security threats, but this is not to say that the security of VoIP is hopeless, in fact, with the frequent occurrence of security incidents, many VoIP manufacturers also in the continuous practice of accumulating experience, through a number of measures to a greater extent to ensure the security of VoIP. But to improve VoIP security to the two-pronged approach, in addition to VoIP vendors to abandon VoIP security is an additional product concept, the security technology is embedded in the VoIP product itself; For VoIP users, to fully realize that VoIP equipment safety straight ...

Currently, VoIP faces security issues of four main: blocking service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. VoIP protocol security is not negligible pain. Information security experts will warn you that if you do not deploy VoIP properly, Internet telephony will be attacked by hackers and malicious code. VoIP can disrupt the security of the network, especially for corporate networks, because companies are eager to deploy this technology and ignore security. Careful analysis can be seen, VoIP first to face the security problem is the lowest ...

Voice Transmission (VoIP) technology based on IP network has developed into a special voice communication technology, and its application is more and more wide. But the study found that, in addition to quality of service issues, security issues are the Chief Technology Officer (CIO) in making VoIP decisions to focus on the content. In reality, many customers say that the security situation does not meet the enterprise's application standards is the reason they do not want to deploy VoIP for the time being. Currently, VoIP faces 4 security issues: Denial of service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. Market research ...

With the continuous expansion of data network bandwidth, hundreds of megabytes or even gigabit to the desktop has become possible. The increase in bandwidth also provides a powerful prerequisite for transmitting voice over the data network. At the same time, VoIP technology is increasingly mature, similar to voice compression, QoS quality assurance, such as the topic has been widely discussed and reached a consensus. It can be said that VoIP technology has been from the original experimental nature of the real specificity for the mature commercial applications. With the continuous expansion of data network bandwidth, hundreds of megabytes or even gigabit to the desktop has become possible. The increase in bandwidth also provides a powerful prerequisite for transmitting voice over a data network.

First, Nat/alg way ordinary NAT is to modify the UDP or TCP message header address information to achieve address conversion, but for VoIP applications, in the UDP net load also need to take address information, ALG means that in the private network of VoIP terminals in the net load to fill in the private network address, This address information is modified to an external address on Nat via Nat. The recognition of voice and video protocols (H323, SIP, mgcp/h248) and the control of Nat/firewall, and each additional new application will require ...

As IP Voice (VoIP) technology continues to spread across the global telecommunications market, performance improvements, cost reductions, and functional support for service providers, device manufacturers, and end-users make VoIP an attractive thing. With increasing interest in VoIP, the security of voice communications is likely to evolve into a key requirement for VoIP solutions. Packet-based communications are particularly vulnerable to security risks, including packet monitoring of voice "eavesdropping", the use of unpaid service to forge network IDs, and manipulation of data packets.
