Asterisk is an open source PBX system and it is difficult to find a detailed description of the asterisk kernel system in public information. Therefore, it is necessary to write a core framework of the description of the document as an internal training document, learn from each other to improve. This paper mainly describes the asterisk kernel from three levels, that is, asterisk kernel module, kernel boot process and basic call flow. First, asterisk

less important Pro3, Pro4 run fewer times. As a result, Pro2 can be completed faster Pro1. Note that only, not the priority will be run two times! In order to achieve the above function, we Linux give the program a so-called "precedence" (priority, PRI), the lower the PRI value represents the higher the priority meaning. However, this PRI value is dynamically ad

For H3C unified communication, we have briefly introduced it in the previous article. Now we will introduce its solution features in depth. Of course, we can also see that these are also the characteristics of the Unified Communication System. In the H3C Unified Communication solution, how do they use this technology to make it more stable and more practical for enterprises? H3C Unified Communication has a hierarchical architecture and open and standard IP technology and interface protocols. It

The Programmable switch, also known as PBX (private branch exchange), is the main channel and bridge between the call center and the outside world.Programmable switchProvides external interface with the local telephone Relay (generally E1 digital relay), and internal interface with the agent representing the phone and automatic voice response device. Programmable switchIt has been widely used in traditional enterprises. In such applications, the num

Looking back at the development process of the Unified Communication Platform, what do we feel? I just think that the progress of science and technology is confusing. Who once thought that the old beacon was a video exchange? Who once thought that the original fast whip, just for a letter, now a bunch of waves can pass your mind. Although the Unified Communication Platform has entered our field of view for a certain period of time, what is unified communication. Some people say that Unified comm

telephone services and dial-up Internet services, it directly encapsulates user data and user line signaling in the IP package. Integrated Access Device (IAD) IAD provides both analog user lines and Ethernet interfaces for accessing common telephones and computer devices. It is applicable to users who use telephone services and computers to use data services respectively. The other type of IAD Only provides Ethernet interfaces for accessing computer devices. It is suitable for users who use bot

found a whole host of modems, hackers have been dialing into the network to continue to look for unprotected or easily guessed passwords on the system. The War dialers preferred Attack object is the "No password" PC remote management software. These software are typically installed by end users to remotely access the company's internal systems. These PC remote control programs are extremely vulnerable when using an insecure modem. Thc-scan is the abbreviation for the Hacker ' Choice (THC) scann

For a growing company, effective communication is as important as the strong business planning of capital operations. But at the moment, small and medium-sized businesses and affiliates are still at a high point when it comes to corporate phone systems. The advent of the network telephony switch has changed this situation. The traditional telephone switch uses the telephone line to transmit the voice signal, but the network telephone exchange uses the unified network communication equipment and

communication, and give some suggestions to enterprises in terms of purchasing group telephone switches. There are various group telephone systems on the market, analog, digital, and network IP-based products. Which product is truly suitable for the enterprise's own needs? The following items must be considered: Cost factors: financial conditions, number of internal phone calls within the enterprise, overall cost, whether there are too many long-distance flights in the field, whether there are

In the previous article, we introduced SOA and unified communication, including its overall concept and traffic business. Now we will continue to explain SOA and Unified Communication. First, let's review the four methods of SOA in speech. Then, we will introduce the situation of some products and vendors. Four Methods of hybrid speech and SOA Despite the bright future, the market is still in its initial stage, with only four major vendors. Avaya and Siemens work on SOA from the traditional tele

VoIP is a popular technology in the world. Sometimes, when talking about the benefits brought by communication technology, VoIP has won a lot of praise. More and more enterprises are migrating their telephone systems from traditional PBX to ip pbx or IP Centrex of VoIP. The traditional production of PBX is gradually decreasing, and network telephone is becoming t

entirely on the state of the function called, similar to the closure structure, this will point to the window Global Object. Through the call, you can specify the this value in the call function. JS classes are generally written into closures, and prototype is used for objects. Prototype and function objects are the most special of JavaScript (I personally think the coolest part, the key is that the writing is very flexible and the reading structure is very clear ), so I generally like to use
