Open Source Advantage

Asterisk is designed on an open source platform, it was originally released by open source developer Mark Spencer of Digium, but has since matured rapidly due to the coding expertise of open source developers all over the world. Its open source nature gives it several distinct advantages over traditional closed software. Advantages of open source software:

  1. Cost. Open source software is typically free to use. There are paid commercial support options available, but the software and framework are free, and without future obligation to pay.

  2. Security. Traditional software can takes long periods of time to patch security vulnerabilities. Open source software can be patched nearly instantly by any developer who uses the software.

  3. Features. Asterisk was launched in 1999 by a single developer. Now it is the most popular open source framework for computer communications in the world. The reason for this is its open source nature, which allowed it to mature a high rate, since any developer, from any part of the world, can contribute to the code to improve it. More and more features are continued to be added by the global team of developers.
