What is an IP PBX?

Asterisk, how to install

Before I start to explain what Asterisk is and what it is for, you should first know what is a telephone switchboard if you still don't know. Well, a switchboard is nothing more than a series of hardware / software devices to center all the telephones in an office, building or area, establishing connections with different users.

In the case of referring to a IP switchboardIt is simply the same, but it will use LAN and WAN networks, using IP protocols to make connections. That is, instead of using traditional telephone networks, VoIP services are used over the Internet.

Sure you had to call More than once to public administrations, health services, or companies, where they have kept you waiting while an agent was free to assist you. Or maybe you have answered some questions to a virtual assistant who has then passed you to the appropriate department according to your needs. Well, that system is precisely a telephone switchboard ...

Asterisk is a free and open source software designed to create communication applications, such as IP telephony systems, VoIP Gateways, conference servers, and other customized solutions for your company or organization. That is why it is so used by many agencies, governments and companies.

It is in constant development, therefore it is a very live project with constant updates and fixes. For all this, it has established itself as one of the main engines of IP-based PBXs in the world.

Although it was initially created as switchboard software, other necessary components were later added to make a complete and powerful communications system. What's more, Asterisk is scalable, another of the strong points if you plan to adapt it to entities of all kinds of sizes.

Why is it the world's leading platform?

Asterisk is not just any platform, it is one of the leaders as I have already mentioned. It allows you to create a switchboard based on this project and that is fully functional. Also has features that stand out compared to other similar services:
