How To Make A 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 ...

Even today, VoIP technology is widely used, security is still repeatedly questioned. Peter Cox, a British security expert and founder of the firewall company Borderware, announced recently that VoIP phones based on the internet are extremely insecure and easy for hackers to exploit. To substantiate this view, he developed a "proof-of-concept" (proof-of-concept) software siptap that could eavesdrop on VoIP Internet telephony. The software utilizes a Trojan horse software installed on the corporate network to successfully access the VoIP network ...

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.

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 ...

Refusing VoIP does not mean that it will not become the mainstream of the future. The controllability, flexibility and economic advantages of technology make it applicable to many places. But at the moment it has some problems that are enough to challenge it. Refusing VoIP does not mean that it will not become the mainstream of the future. The controllability, flexibility and economic advantages of technology make it applicable to many places. But at the moment it has some problems that are enough to challenge it. After decades of technical hurdles and poor connectivity, VoIP has finally become a choice. It seems to have become the necessary technology today ...

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.

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 ...

To do an image analogy: The server is like a post office switch, and computers, notebooks, PDAs, mobile phones, such as fixed or mobile network terminals, such as scattered in the home, all kinds of office space, public places, such as telephones ...

Open source Hotspot Inventory 1984, Richard Stallman launched GNU and Free Softwarefoundation, which has been open source for more than 28 years. From the bottom of the operating system to advanced desktop applications, there are open source footprint. Linux, which is especially open source operating system, is a controversial issue and is subject to many commercial attacks. 　　Many people like to put open source and business together, to accuse Open source is how "irregular", "energy consumption", "instability" and so on, especially Microsoft.
