Asterisk PBX has a set of custom configuration file formats. It reads and writes configuration files through a built-in configuration file parser (parser. After asterisk 1.2, the configuration file format has been improved, and the support for template configuration has been added. The template configuration greatly improves the flexibility and scalability of the configuration. The configuration file is improved at the general configuration parser le

telephone service. Your phone is just a trivial terminal device, and the function is very simple. Even though some telephones have the function of call waiting, call forwarding, and call keeping keys, the implementation of these functions still relies on the support of the switch. The switch provides everything (even power) to the phone, and any signal sent on the phone, whether it is a button operation or your voice, must be managed and converted by the switch. As a result, all telephone conne

Phone mode. 1. The General Voice Gateway access method is to use a dedicated voice gateway device to connect the voice program-controlled switch and WAN link; 2. the router access method uses the voice processing function of the existing vro to connect a traditional analog phone to an IP network; 3. The IP Phone method uses a soft PBX. For example, Cisco Call Manager is used as the telephone management center and a vswitch is used to connect to an IP

The adapter mode is to convert an interface of a class to another interface that the customer wants, so that those classes that cannot work together due to incompatibility of the interface can work together. I don't know if you have used the adapter mode in daily coding, but the working mode of the adapter is very common in our life. This article uses the oldest but most representative example to explain. Now there is an electrical appliance worth 1

Many people want to know whether it is possible to build an enterprise-class open source VoIP solution and whether it is good to do so. This paper gives some positive answers to this question.

Specifically, it is based on hellm, a general term for Iot operating systems and platforms. Therefore, this smart home framework is also known as the hellm Smart Home framework ". The overall architecture diagram is as follows: It looks complicated and is easy to understand. In the figure, the dark red entity (or module) is a component contained in

As enterprises move towards server virtualization, does the VoIP/ipserver adapt to the server consolidation plan? The answer is yes. PBX (Programmable switch) was previously an independent proprietary system. With the emergence of Internet protocol Voice Technology (VoIP) and network telephone technology (IPTS), PBX has become a system-based server. Why Should organizations and their ability to virtualize V

are for this reason). However, there are also many enterprise accounts out of high value Return Considerations: 41% of companies say they can use VoIP to build an all-in-one communication platform, 36% of companies want to increase collaboration by integrating voice and data sharing, video conferencing, or online notification Technology. For whatever reason, VoIP will be a direction for enterprise applications. In the near future, it will become the main way for most enterprises to communicate.

In the process of learning the SIP protocol, we need to be clear about a concept, that is, the concept of SIP relay. In order to help you better understand this aspect, we use a comparison between Chinese and English translations to help you understand this aspect. The specific information is as follows: A sip Trunk is a logical connection between an ip pbx and a Service Provider's application servers that allows voice over IP traffic to be exchanged

scenario first emerged, followed by the ins and outs and needs of these problems, followed by the evolution of some design schemes, and finally some of them were standardized as models. Therefore, we will try to understand and analyze some examples of the design patterns we discuss in real life, and then try to summarize a design step by step, and finally summarize some designs that match some patterns. Design Patterns are discovered in these similar processes. What do you think? Farhana: I th

PBX. The phones on the network use the existing architecture to call VoIP phones. Many large enterprises choose to replace PBX with ip pbx without changing the installed internal telephone lines, saving the company the cost of replacing all telephones. Citel, Intel, and other companies provide such phone gateways. VoIP Interface The VoIP interface is a interfac

For enterprises, the former means to save operating costs, while the latter helps to improve work efficiency and improve service quality. Enterprise-Class VoIP applications, including VoIP technology based on the relevant value-added applications, mainly voice connection business, IP video conferencing business, LAN telephone, call center, IP video Conferencing business, a variety of. 　　It can be said tha

When talking about open source IP-PBX, people familiar with this field probably know AsteriskThis famous open-source ippbx. There are many technical documents about asterisk. However, what I want to introduce here is another ippbx solution, which is also an open-source system- Sipxecs. I checked Chinese information and introduction about sipxecs through Google and found that there were not many, obviously it was no longer popular with asterisk. Howeve

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 security of the voice gateway device. 1.1 Login Password Management Strengthen the maintenance an

provides both voice and data interfaces. If you have an integrated access device, make sure it can be upgraded to a full-featured router with new software before changing it. The "VoIP" that appears here is only the data-based voice data between the external connections of the PBX. For enterprises with more than one site, a good start is to replace the current direct connection telephone line with VoIP between different sites. In this step, you do no

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
