Multiple security vulnerabilities in Portech MV-372 VoIP Gateway Release date:Updated on: Affected Systems:PORTech MV-372Description:--------------------------------------------------------------------------------Bugtraq id: 48560 The MV-372 is a 2-channel VoIP GSM/CDMA/UMTS gateway for call terminals (VoIP to GSM/CDMA/UMTS to

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

Fluke Networks Fluke Network) recently released a new NetTool II series online network multimeter with the NetProve diagnostic function. It diagnoses Enterprise Network and application connectivity faults four times faster than traditional methods.The newly released NetTool II series has a simple one-step NetProve test function, allowing technicians to quickly and conveniently identify the root cause of the problem regardless of their expertise. The NetTool II series can identify whether a fault

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

The Cisco SIP VoIP architecture solution provides users with many services. The table lists various IP telephone services that can be implemented by Cisco SIP VoIP Architecture solutions.Cisco SIP VoIP architecture solution ComponentsThe Cisco SIP VoIP architecture solution consists of the following elements:Sip ip tel

In recent years, broadband services based on IP technology have become increasingly popular. As a result, H.323 multimedia communication systems are no longer limited to private network user groups. Moreover, they are increasingly favored by Internet-based enterprise users. With the gradual popularization of H.323 system applications on the Internet, the conventional problem of firewall and NAT traversal has encountered new challenges, and this contradiction is becoming increasingly apparent. Co

On June 23, March 8, Microsoft said on Tuesday that Internet telephone (VoIP) will bring "billions" of dollars in revenue to enterprises. According to Reuters, Jeff Raikes, president of Microsoft's Enterprise Department, said Internet calls will become popular in the next three years, and Microsoft's new server software will change the entire communication system industry, just as its Windows operating system changed the computer industry. Before givi

The original name of David Sims's article is "seven successful VoIP services in seven steps", it aims to help ISP or traditional telephone companies respond to the requirements of enterprises interested in VoIP services. However, this Guide applies to anyone interested in VoIP, even if their enterprise scale is small. Few of these steps involve enterprise-level i

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

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
