In addition to the C compiler, you'll also need a set of system libraries. Essential libraries are used by Asterisk and must be installed before you can compile Asterisk. Core libraries allow compilation of additional core supported features. On most operating systems, you'll need to install both the library and it's corresponding development package.
- Installing libsrtp
We recommend you use the package management system of your operating system to install these libraries before compiling and installing Asterisk.
