The knowledge about IP PBX

Based on our nearly 3 years of project experience, more and more customers use VOIP SIP emergency telephones and SIP telephone systems to design and build communication systems. For SIP telephone systems, IP PBX is a very important part.

Why do we need IP PBX?

The traditional circuit-switched voice exchange (PBX) has been developed for decades, but it has been difficult to adapt to new customer needs. The rapid development of the Internet with TCP/IP technology as the core has spawned a large number of businesses. The traditional TDM-based PBX can hardly meet the needs of the new era.

In terms of business types, PBX only meets the needs of enterprises for making phone calls and inter-extension dialing, and for such needs as voice mailbox, recording, and CRM integration. Although it can be achieved through some specialized means, the implementation is complicated, poorly stable, and poorly manageable. These will become the “bottleneck” for the enterprise’s future unified communications and business integration.

What are the significant advantages of IP PBX?

The openness and versatility of IP have brought new ideas to the evolution of PBX. The IP-PBX with IP switching as the core can not only complete the traditional voice switching function, but also realize all the services supported by the traditional PBX, such as call transfer, DID, conference, wake-up, resonance, ring vibration, etc., but also realize voice mailbox and recording, Integration with CRM, IP bypass, customized ring back tone, remote extension, etc.

The story of IP PBX and Asterisk

Asterisk is the most popular communication open-source software worldwide, which provides an important source for the rapid development of IP-PBX. According to incomplete statistics, there are currently tens of thousands of businesses around the world developing their own IP-PBX or similar voice products based on Asterisk, and many large enterprises embed it in their office software. There is a lot of open-source software in IP communication. Here we take Asterisk as an example to give a brief introduction.

In 1999, a Linux consulting and service provider, American Mark Spencer developed the most original IP-PBX software for his own needs, and gave this software a name called “asterisk”. We know that in In DoS or Linux, the asterisk means “wildcard”. He wants his software to be omnipotent. His next move was very interesting. He put this software called Asterisk on his website for others to download and use. Surprising things happened. More and more people began to ask him about this software. Later, he established a company named “Digium”.Specially provide Asterisk technical support, and began to produce and sell matching boards. Since Asterisk is open-source software, more and more programming enthusiasts and communication enthusiasts have joined it to continue its development. After unremitting efforts, more than 100,000 “patches” have been applied to make this open-source software shine.

About the development of IP PBX

In fact, discussing the functions of IP-PBX does not have much meaning. After the development of IP communication, any definition of the name and function of a certain type of product has become difficult. The reason is that various technologies are integrated with each other and are all implemented on the IP platform, making it difficult to use traditional concepts to evaluate a certain historical term. For example, traditional switches emphasize the “number of ports” of it, which becomes difficult to describe on IP-PBX. For an IP-PBX without an interface, can the number of SIP registrations be counted as the “number of ports”?

The changes that IP technology brings to us are profound and far-reaching. It is difficult for you to use traditional communication concepts to understand today’s IP-based products. This may be even more so in the era of mobile Internet. It is from the height of “unified communications” that you will find that IP-based voice is an extremely important link in future corporate communications. Voice is closely integrated with enterprise information flow, data flow, and management process, becoming a bridge and link for future telecom operators and ISPs to provide services for enterprise informatization, and a stage for the application of various telecom services in enterprises in the future!


With VoIP and IP-PBX, it is not difficult for us to understand distributed call centers. Under the impact of the indestructible IP technology, the call center is undergoing a rapid transformation.

The first change is the redefinition of the market served by call centers. For most of the past, call centers have been providing services to large companies and are a luxury in the “rich man’s club.” Once the call center introduces IP technology, it is logical to draw SMEs to the camp of call center users.

The second transformation is that IP communication can easily solve the problem of remote communication. Extensions can be distributed anywhere in the world and managed by a unified organization. This is a distributed call center. Many people refer to the distributed call center as IPCC for short, which means “IP-enabled Call Center”. The call center adopts a distributed architecture, which has great social significance and economic benefits. Extensions of distributed call centers can be built in multiple cities, multiple countries, or regions as needed. Each agent can use unified messaging technology to store the user’s name, address, phone number, email address, product purchase history, service history, customer’s geographic location, or language preference under a unique account identifier, allowing customers always feel like someone who knows them well is communicating with. This model has the ability to create a unified set of applications and brings great flexibility to the call model. IPCC is more like a huge road roller. It does not flatten a certain road in the city, but flattens the whole world!
