Installation StepsIt is recommended that you use the most recent version of the Asterisk, DAHDI, and libpri software for the best results. If you have previously installed any of these, Digium recommends that you upgrade to the latest “-current” version of each.
Also, please be aware that you may need to re-compile Asterisk if you are upgrading DAHDI or libpri. The Application programming interface (API) of these packges tends to change between versions, re-compilation is the only way that you make Asterisk's adapt to the new API.
