, because a large number of NAT/FW devices have been deployed on the network, in practice, it is difficult to use this method. MIDCOM Method Unlike NAT/ALG, the basic framework of MIDCOM is to use a trusted third-party (MIDCOM Agent) to control Middlebox (NAT/FW). The identification of VOIP protocols is not completed by Middlebox, it is implemented by the external MIDCOM Agent, so the protocol used by

this time, the SIP user name will change to the phone numberChoosing a VoIP operator (select a VoIP operator) The Linphone project is not affiliated with any VoIP or telecom operator, thus we do not recommend or promote any of them in participates. by typing "VoIP operator" in your favorite search engine you will get

Both VoIP and WiMAX pose a threat and challenge to traditional technologies in their respective areas. The combination of them will also make new demands and new effects on the development of communication technology. Priority support for VoIP services For WiMAX, VoIP voice service as a basic business type must be supported first. WiMAX network based on IP

between Headquarters and branch nodes can save the high cost of renting long-distance circuit relay. Therefore, VoIP technology will be widely used in enterprise users. However, in the implementation project or in the use process, users and equipment suppliers will focus more on how to improve the voice quality and integrate with existing data networks, the security risks of VoIP are rarely considered.

complex system engineering and has a wide range of applications. Therefore, many technologies are involved. The most fundamental technology is the VoIP (Voice over IP) technology, it can be said that Internet voice communication is the most typical and promising application area of VoIP technology. Therefore, before discussing the use of the Internet for voice communication, it is necessary to analyze the

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

requirements. This prevents shutdown and repair failures when the VoIP device is installed on a cable with insufficient bandwidth. The Toolbox also contains NetTool with VoIP test options.™Series II online network multimeter. NetTool allows users to deeply observe VoIP calls by installing NetTool between IP phones and networks. Users now can quickly diagnose the

Pjsip is an open source SIP protocol stack. It supports a wide range of SIP extensions and is arguably one of the most popular sip stacks. It implements SIP, SDP, RTP, STUN, turn, and ice. PJSIP provides a very clear API as well as NAT traversal capabilities as a SIP-based multimedia communication framework. Pjsip is very well-ported and supports almost all today's systems: from desktop systems to embedded systems to smartphones. Pjsip also supports v

Whether it is internal communication, or communication between enterprises and customers, it will be a huge application field of fusion communication. Converged Communications Service is based on the ability to provide voice, data, video and multimedia business information and communication technology to carry out a full range of business ser

packets. When VoIP is used on a busy and congested network, it is difficult to compensate for Jitter at the receiving site and the sending site. Caching voice communication at the receiving end helps compensate for jitter. In fact, the conversation is stored until it is sufficient to be sent to the receiver. The TCP/IP protocol transmits data packets based on several routing algorithms. To make

vulnerabilities. The Zfone software is based on a new protocol developed by Zimmermann called "ZRTP". Although the initials are not expanded in Zimmermann files or Web pages, it is possible to guess that the acronym means "Zfone Real time Protocol" (Zfone Real-time Protocol), or "Zfone Time Protoco "(Zfone Security Real-time

The VoIP network protocol is the basis of the network telephone. It has been widely used in network communication. The use of this Protocol forms this business and challenges the traditional communication market to the maximum extent, and traditional communication methods. Let's take a look at this powerful VoIP.

What is VoIP? The complete name of VoIP is voice over Internet protocol, which is translated as Internet voice. It can be simply understood as a technology that uses an Internet system instead of a traditional telephone communication system for voice calls. In fact, the biggest difference between the two is that traditional voice calls use analog signal technolog
