Currently, VoIP faces security issues of four main: blocking service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. and 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.

Overview explanation VoIP is the abbreviation for voice over Internet protocol, meaning to transmit voice over the Internet (Internet). VoIP technology is also often referred to as network telephony, IP telephony, or Internet telephony technology. VoIP's most basic function is to provide internet-based, low-cost voice and fax services. It can also extend further to ip-based voice services.

Author: OrphousV Tianyang ForumThis time I will show the implementation process of several common attack forms.SIPSession Initiation Protocol (ietf rfc 3261) is a widely used VoIP Protocol. SIP is responsible for creating and disabling multimedia sessions, and VoIP involves multimedia sessions. In a phone conversation, the SIP message exchange method 1 is shown.Figure 1First, the User Agent (User Agent), th

At present, most enterprises in China have already connected to the data network and started to carry out various services, such as office systems, on the network, how to enable your data network to bring more benefits to enterprises is already a very realistic problem for enterprises. On the one hand, we consider using the data network to improve production efficiency, on the one hand, it is highly cost-effective to consider cost savings through data networks, especially for those enterprises w

From the security point of view, VoIP is ineffective, and it has both network and voice network weaknesses. However, the security challenges faced by VoIP are not unsolvable. All we need is a complete security plan. Step 1: three major security threats of VoIP are authentication failure, integrity failure, and privacy protection failure. When implementing

1 Introduction At present, the telecom operation mode is facing a huge change. The traditional telecom business is undergoing profound changes in terms of concepts, technologies, businesses, investment, management and services. The new communication mode will be unified to the IP address. The VoIP (Voice over IP) uses the speech compression encoding technology, the grouping real-time transmission technology and the Control Protocol (RTP/RTCP) the tech

Many enterprises are considering migrating to VoIP. Network administrators have many considerations. The SearchVoIP.com website interviewed Doug Hyde, product line manager of the stack switch of 3Com, about some tips on mitigating this transition and ensuring that the network is ready for VoIP. Q: How can enterprises ensure the service quality of existing networks? Doug Hyde: an important aspect of ensuring

With the development of China's routing industry, we have also promoted the update and upgrade of the VoIP router technology. Here we mainly introduce how to do a good job in the security vulnerabilities of the VoIP router technology. As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful precon

VOIP, also known as IP phone or IP phone, is the abbreviation of Voice Over IP. This technology is used to encode, digitize, compress, and compress Voice signals into Compressed Frames, then, the IP packet is converted to the IP packet for transmission over the IP network, thus achieving the purpose of voice communication over the IP network. The IP Phone greatly improves the utilization of network bandwidth and reduces the communication cost. its wid

VoIP has become a major topic in the era of integration. How to better utilize the functions of VoIP in the aspect of open-source and throttling, and reduce the communication costs of enterprises and individuals has also become a common concern in the industry. At the beginning, as a technology used in Internet applications, VoIP was widely loved by Internet user

As VoIP continues to replace analog phones in the enterprise voice communication market, this technology is also rapidly adopted in residential environments and Small and Medium-Sized Enterprises (SMBs. The advantages of VoIP, such as multiple lines, the use of cheap digital media voice communication systems, and significantly reduce the communication rate, not only for large enterprises, but also for small

on mobile voice services, however, the performance evaluation results of traditional MANET for VOIP services are always unsatisfactory. Here, people are very concerned about whether the wireless mesh network can meet the quality requirements of users for real-time voice services. Iometrix, a professional testing company, conducted the first performance evaluation and testing of Wireless Mesh Networks Based on the draft study by the IEEE 802.11 Workin

We now have a lot of knowledge about VoIP technology, and we are almost at risk to talk about other applications and usage knowledge. In the use of VoIP technology, we will transmit voice signals in the IP network. However, there are also many technical needs to achieve long-distance IP network spanning. ◆ Session edge controller SBC) Technology Session edge controller SBC, or session Controller) is a
