Problem description: When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files. Problem Analysis: These problems are often caused by the identification of data packet fragments by devices during data transmission. Generally, data packets are too large and nee

Application VoIP service quality (QoS) has four key steps. If you do not follow these four steps, your VoIP implementation will not realize its full potential. In addition to enabling the vro function, QoS has many things to do. Therefore, it takes some time for you to plan and design the correct QoS for your speech environment. The following are the four key steps: Step 1: classify your voice communication

For now, the cost of long-distance calls is still very high. In the VoIP service, the most attractive is its low cost. Next we will introduce the VoIP protocol. We hope you can understand it. VoIP protocol Currently, VoIP protocols are commonly used, such as H.323, SIP, MEGACO, and MGCP ｡ H.323 is a ITU-T standard orig

VoIP is a transmission technology that uses a router-Based IP group switching network to implement voice communication. The biggest advantage of VoIP technology is that IP Phones only require 8 kbit/s to use advanced voice encoding technology ~ The bandwidth of 12 kbit/s can be transmitted much less than the 64 kbit/s of the traditional circuit switching network. Wireless

Readers who have a long memory and a history of online trading may also vaguely recall that the creator of the famous PGP (Pretty Good Privacy) software, security expert Phil Zimmermann, launched a "Pgpfone" in 1996. of Internet telephony products. About three years later, broadband networks really started to grow. This is the early stage of the network telephony development cycle. Pgpfone a little too far ahead, not to arouse people's attention. But the world must be careful! Security expert Ph

In the case of Voip, we often encounter customer requirements for public-specialized functions. The general practice is to connect the FXO interface to the extension line. The customer calls in through the external line, hears the automatic operator, then dials to the VOIP extension, and then calls the IP address, however, this practice usually requires some vswitches. PBX has a type of group telephone. T

QoS Assurance Measures for VoIP services are currently the topic most discussed in the industry. IETFInternet Engineering Task Force) several technical solutions to support QoS are recommended, mainly including: Integrated Service Int-serv) /Resource Reservation Protocol (RSVP), Differentiated Services (DiffServ), Multi-Protocol Label Switching (MPLS), and business Traffic Engineering (Traffic Engineering. Telecom operators have also adopted some meas

When enterprises integrate data centers and voice technology, they may consider meeting the environmental conditions required for the operation of new devices in advance. However, when enterprises switch from a TDM-based phone to an IP phone, meeting the needs of the wiring room environment is often ignored. When deploying an IP phone to a desktop, users will soon face the same problems as local broadband providers. These problems may cause the system to fail to run normally, or cause higher cos
