managing traditional PBX. We can see that most of the security problems faced by VoIP are actually problems faced by IP networks. Therefore, the conventional security measures must be ensured first. In addition, the special characteristics of VoIP applications require special measures to enhance security. Below I recommend several small preventive measures. These measures may not use any advanced technology, but these measures may help your network b

faults in the early stages of the system and reduce the confusion of end users, in addition, by introducing the company's original PBX system and telephones into a new unified communication system, the overall deployment cost is reduced. The company's Unified Communication System uses ShoreTel's equipment. "Taking full advantage of the old telephone system and integrating it into the new Unified Communication System can reduce deployment costs, so we

, and conference costs. Through meetings and UC solutions with collaboration capabilities, such as audio/Webpage/video meetings, as well as shared workspace and file sharing, travel needs can be reduced or even canceled, this saves hundreds of thousands or even millions of dollars. Using the Conference function in the room rather than using the service also reduces the cost. In the world of UC, communication functions have become software applications, reducing the need for multiple servers in e

installation command is relatively simple. If you have not installed qemu before, run the following two commands to install qemu. $ Sudo apt-get install qemu-kvm www.2cto.com $ sudo qpt-get install qemu-kvm-extras I installed qemu on Ubuntu, so you only need the following command: $ sudo qpt-get install qemu-kvm-extras after installation, run the following command to view the supported machines: $ qemu-system-arm-machine? The output results on my side are listed below. If you want to use qemu t

?Let me explain it in detail. For example, enterprises generally have windows Linux servers. How can we quickly shut down these servers?(How long does your UPS support? How long can the temperature of your air conditioner remain below 30 degrees after it is stopped ?) So here we will solve this problem. 1. The shutdown process refers to the process of regulating what the equipment in your data room should be shut down first. If a small number of servers needTo supplement the need for intermitten

computers to the main system. If the business needs to be connected, you should also register with the relevant departments of the company and change it to the "out-of-box" dialing method. Enterprises must also have clear regulations in this respect. Some people think that the PBX uses a digital line and no one can install the modem without authorization. This is a big mistake! Because digital modem lines are cheap and easy to buy. In addition, enter

What are the appropriate benchmark numbers for IP router management? For example, to monitor and maintain 1000 routers and 1000 lines, how many employees need to be configured for each shift? To develop a standard for resources, we generally try to estimate the number of network devices that can be managed by each resource as follows: · Highly complex network devices: 15 to 20 employees. · Moderately complex network devices: 60 to 75 employees each. · Low-complexity network devices: 250 to 3

integration, network architecture integration, and application platform integration. What is the difference between integration and unification? Huang yanwen believes that unification can be said to be the sublimation of integration, but it is actually a step-by-step development process. If there is a difference, it is the business model. In the past, integration was more about the integration of architecture and application systems. In the Unified Communication technology system, a system and

, can contain six major components: Voice, information transmission, presentation and IM instant messaging), mobility, conferencing, and APIs application interfaces ). These six parts are the basic components of Unified Communication. There is no doubt about the role of speech in the Unified Communication Technology System. In fact, many Unified Communication systems are based on speech and belong to the extension or expansion of PBX. Information Tran

The current communication methods are inseparable from the IP network. To combine the two, you must use the gateway. Now let's talk about the knowledge of Cisco's unified voice gateway. Which models are available in these products, and what are the differences between these models? Cisco Unified Communication Voice Gateway Cisco 1700, 2600XM, 2800, 3700 and 3800, and Cisco Catalyst? The 5000 Series Voice Gateway Router uses SIP to terminate a call and convert the call signal between the PSTN and

When possible, a low-cost service contract should be used to obtain new software features to prolong the service life of the purchased software. If necessary, consider using centralized tools to deliver new software to devices. 7. network security vulnerabilities are b
