Getting started with baresip

Before attempting to install baresip on your GNU/Linux distribution using the tarball provided by Softpedia on the dedicated download section above, keep in mind that you must first acquire and install the libre and librem libraries.

Once the aforementioned libraries have been correctly installed on your Linux kernel-based operating system, you can download the latest baresip code from Softpedia or via its official website (see link below), save the archive somewhere on your computer and unpack it.

Open a terminal emulator, navigate to the location of the extracted archive files with the ‘cd’ command and execute the ‘make’ command to compile the program. After a successful compilation, you can install it system wide using the ‘make install’ command as root or the ‘sudo make install’ command as a privileged user.
