baresip is using GNU makefiles, and the following packages must be installed before building:
$ make
$ sudo make install
$ make RELEASE=1
$ sudo make RELEASE=1 install
$ make CC=clang
$ sudo make CC=clang install
Modules will be built if external dependencies are installed. After building you can start baresip like this:
$ baresip
The config files in $HOME/.baresip are automatically generated the first time you run baresip.
Configuration examples are available from the examples directory.
The baresip project is using the 3-clause BSD license.
Patches can be sent via Github Pull-Requests or to the Baresip mailing-list.
