Recently, various attacks against VoIP voice gateway devices have frequently occurred, causing many troubles and economic losses to customers. In order to further prevent the VOIP Voice Gateway from being compromised by a network attack or attack, the network technology provides several preventive measures for the security of the voice gateway device, ask the customer to take measures to prevent the securit

What is gateway? gateway is also called the inter-network connector and Protocol converter. The gateway is the most complex network interconnection device on the transport layer to achieve network interconnection. It is only used for different network interconnection between two high-level protocols. The structure of the gateway is similar to that of the router. The difference is the Interconnection layer. Gateways can be used for both Wan and LAN interconnection. What is a

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 voice, video, status rendering, and instant me

architecture? In the fuzzy definition of NGN, some people think that Softswitch is NGN, while others think that the traditional PSTN voice service supported by Softswitch is the whole of NGN. Yin Kang, Cisco's Asia Pacific NGN/VoIP chief technical consultant, believes that the ambiguity of the Softswitch technology concept reflects the industry's misunderstanding of softswitch in some aspects, there is a situation where the capability of one aspect i

VoIP Voice IP) or Internet telephone technology refers to the Communication Service-voice, fax and/or voice and information applications transmitted through the Internet rather than the public exchange Telephone Network (PSTN. The basic steps involved in sending Internet phone calls include converting analog voice signals into digital voice signals and compressing signals into Internet Protocol IP addresses) information packages for transmission over

1 Introduction VoIPVoice over IP is a technology that uses an IP network for voice communication. As IP technology is a connectionless technology, the original intention of an IP network is to provide a service called "Best Effort" and "Best Effort, this is suitable for data services that only require accuracy and have no strict requirements on latency. For real-time communication services such as voice and video, their Service Quality is of Service and QoS) it is hard to guarantee. The

How can I obtain domain administrator permissions through VOIP Intranet evaluation? Through the internal VOIP evaluation, we scanned port 5060 and port 5061 to find the IP phone that has been started. Then we found a range and started to connect to the web page with port 80 enabled for each phone. Check the status message of the VOIP Phone. We found that the ph

Label: style blog HTTP Io OS AR for strong sp You must have heard about IP Phone and SIP (software IP Phone ). nowadays standard PSTN phone are being replaced by IP Phones one of the main reason why companies are switching towards IP phones is its low cost and easy setup. Blogs Requirement Online phone directory What is VoIP? Voice over Internet Protocol (VoIP) is a general term for a family of trans

One major drawback of using VOIP and video calls is that Nat and firewall restrict the stable completion of calls. Nat and firewall play an important role in security protection and hardening of internal network availability, but they also pose serious problems for establishing VoIP calls between end users.IETF standard stun, turn, and ice are deployed to handle NAT traversal issues. Stun helps

Currently, traffic revenue is growing rapidly, accounting for about half of the operator's revenue. However, traditional voice communication revenue is still the focus of operators. However, in the 2G or 3G era, there is no obstacle in the 4G era. Complicated VoIP implementation, multiple solutions help LTE transition LTE is a full-IP network, and its network architecture can implement VoIP communication. H

Nu Service Shunt configuration:Configure the traffic template.Because VoIP, IPTV, Internet access through the same port, it is necessary to set the 802.1p priority of each business. The general priority is ranked by Internet service, IPTV, VoIP from low to high. Set the traffic template index number here, respectivelyFor 7, 8, 9,802.1p priority is 0, 4, 6 respectively.Huawei (config) #traffic table IP index

No matter whether enterprise users are ready or not, IPv6 network deployment is just around the corner. The demand for advanced site selection technology is growing, and everything in life will be able to use this technology. At the same time, VoIP has become the mainstream technology and has become the basis of other network services. It is no longer the concept of "Next Generation" voice networks. So our worries also follow: What impact will these

Next we will introduce the VoIP protocol. We all know that VoIP is one of the most popular network businesses. The Application Basis of this Service is also a VoIP protocol. We will introduce this protocol in detail. VoIP protocol Currently, VoIP protocols are commonly used,

Voice communication over the Internet is a very 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. This article describes the basic transmission process of VOIP.

grouping network. It also provides users with both voice, data, and multimedia services through a converged network. At the 2006 China Information Industry Economy Annual Meeting, Zhao huiling, Vice President of China Telecom Group's Beijing Research Institute, pointed out: "to achieve integrated services to provide platforms, integrated business management platforms, and portal to differentiate customer groups, this is our long-term goal. Then, we stop Circuit Switching in the entire exchange

The VoIP network protocol is the support for VoIP services. In network communication, the use of this Protocol forms this business, and it is challenging the traditional communication market and traditional communication methods to the maximum extent. Let's take a look at this powerful VoIP. VoIP network protocol Curre

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.
