LI on asterisk

i want to install Asterisk for a local telephone company with a2billing as billing… surely we have to develope those items but the most important things is LI for me

multiSwitch LI module that Allows authorized personnel from national agencies to intercept data from certain calls and send the call to a special LI device

Doest Asterisk support it? if yes how ? do we need to buy any device? or just throw software?
